The|DT meeting|NN discussed|VBD Bruce|NNP 's|POS new|JJ proposal|NN ,|, see|VB :|: http://www.w3.org/pub/WWW/MarkUp/Math/WG/Smith-960531.html|NN 

Dave|NNP asked|VBD about|IN lexical|JJ details|NNS .|. 
For|IN instance|NN if|IN one|CD uses|VBZ an|DT SGML|NNP named|VBD character|NN entity|NN how|WRB does|VBZ the|DT tokenizer|NN know|VB whether|IN the|DT character|NN is|VBZ allowed|VBN as|IN part|NN of|IN an|DT identifier|NN ?|. 
Bruce|NNP replied|VBD that|IN there|EX needs|VBZ to|TO be|VB a|DT large|JJ dictionary|JJ that|WDT specifies|VBZ properties|NNS such|JJ as|IN :|: 
o|NN Whether|IN the|DT character|NN is|VBZ allowed|VBN as|IN the|DT first|JJ or|CC subsequent|JJ characters|NNS in|IN an|DT identifier|NN .|. 
o|NN If|IN it|PRP is|VBZ an|DT operator|NN ,|, its|PRP$ types|NNS (|( prefix|NN /|NN infix|NN /|NN postfix|NN )|) and|CC the|DT associated|VBN left|VBD and|CC right|JJ precedences|NNS .|. 
o|NN Whether|IN it|PRP can|MD be|VB used|VBN to|TO embellish|VB other|JJ operators|NNS .|. 

Action|NNP :|: Bruce|NNP to|TO add|VB a|DT detailed|JJ schema|NN for|IN the|DT character|NN dictionary|JJ .|. 

Dave|NNP also|RB suggested|VBD that|IN as|IN a|DT matter|NN of|IN principle|NN any|DT tag|NN names|NNS should|MD have|VB meaningful|JJ names|NNS .|. 
Bruce|NNP said|VBD he|PRP wanted|VBD to|TO avoid|VB potential|JJ naming|NN conflicts|NNS with|IN other|JJ groups|NNS wishing|VBG to|TO define|VB new|JJ HTML|NNP tags|NNS .|. 
Dave|NNP said|VBD that|IN this|DT was|VBD n't|RB a|DT big|JJ problem|NN ,|, given|VBN W|NNP 3|CD C|NNP 's|POS role|NN in|IN defining|VBG HTML|NNP .|. 

Action|NNP :|: Dave|NNP to|TO post|VB a|DT proposal|NN for|IN the|DT HTML-math|NNP tag|NN names|NNS .|. 

Robert|NNP added|VBD that|IN to|TO allow|VB him|PRP to|TO implement|VB the|DT proposal|NN he|PRP would|MD need|VB more|JJR detail|NN on|IN the|DT various|JJ layout|NN schema|NN .|. 
Bruce|NNP will|MD work|VB on|IN this|DT .|. 

Dave|NNP queried|VBN the|DT flat|JJ associativity|NN with|IN same|JJ precedences|NNS for|IN `|`` +|NN '|'' and|CC `|`` -|: '|'' .|. 
Neil|NNP explained|VBD that|IN this|DT makes|VBZ it|PRP much|RB easier|JJR to|TO write|VB the|DT line|NN breaking|VBG algorithm|NN .|. 

Macro|NNP definitions|NNS .|. 
Bruce|NNP will|MD add|VB an|DT SGML|NNP element|NN to|TO represent|VB these|DT .|. 
This|DT raises|VBZ the|DT issue|NN of|IN scoping|VBG and|CC how|WRB a|DT plug-in|JJ could|MD exploit|VB the|DT HTML|NNP parse|NN tree|NN .|. 
In|IN the|DT short|JJ term|NN ,|, this|DT will|MD remain|VB a|DT problem|NN .|. 

We|PRP discussed|VBD the|DT representation|NN for|IN arrays|NNS .|. 
Dave|NNP explained|VBD that|IN the|DT HTML|NNP 3.0|CD proposal|NN borrowed|VBN from|IN LaTeX|NNP and|CC TeX|NNP .|. 
See|NNP :|: http://www.w3.org/pub/WWW/MarkUp/html3/arrays.html|NN 

It|PRP supports|VBZ :|: 
o|NN setting|VBG position|NN of|IN array|NN relative|JJ to|TO preceding|VBG and|CC followng|NN expressions|NNS 
o|NN column|NN specification|NN for|IN cell|NN alignment|NN 
o|NN cells|NNS spanning|VBG multiple|JJ rows|NNS or|CC columns|NNS 
o|NN "|'' +|NN "|'' ,|, "|'' -|: "|'' or|CC "|'' =|SYM "|'' characters|NNS as|IN column|NN separators|NNS 
o|NN separation|NN of|IN first|JJ row|NN /|NN column|NN as|IN labels|NNS 
o|NN setting|VBG left|VBN and|CC right|JJ bracket|NN symbols|NNS 
o|NN filling|VBG a|DT cell|NN spanning|VBG several|JJ columns|NNS with|IN dots|NNS 

The|DT features|NNS needed|VBN for|IN math|NN make|NN it|PRP inappropriate|JJ to|TO use|VB the|DT HTML|NNP table|NN tags|NNS .|. 

We|PRP discussed|VBD what|WP HTML|NNP tags|NNS might|MD be|VB appropriate|JJ within|IN HTML-math|NNP .|. 
The|DT current|JJ inability|NN to|TO call|VB the|DT browser|NN to|TO handle|VB such|JJ nested|JJ tags|NNS suggests|VBZ we|PRP need|VBP to|TO take|VB a|DT cautious|JJ approach|NN .|. 
A|DT the|DT minimum|JJ we|PRP probably|RB need|VBP :|: 
o|NN plain|JJ text|NN 
o|NN simple|JJ kinds|NNS of|IN emphasis|NN (|( bold|JJ /|NN italic|JJ )|) 
o|NN control|NN over|IN font|NN size|NN 
o|NN hypertext|NN links|NNS 
o|NN line|NN numbering|VBG 

We|PRP could|MD further|RB allow|VB this|DT text|NN to|TO include|VB math|NN elements|NNS so|IN that|IN we|PRP get|VBP math|NN including|VBG text|NN including|VBG math|NN etc.|NN 
This|DT does|VBZ n't|RB seem|VB to|TO be|VB needed|VBN in|IN practice|NN though|IN .|. 

The|DT current|JJ plug-in|JJ api|NN 's|POS are|NN inadequate|JJ .|. 
For|IN instance|NN one|PRP would|MD like|VB to|TO know|VB the|DT current|JJ font|NN family|NN ,|, size|NN and|CC baseline|NN position|NN ,|, as|RB well|RB as|IN the|DT background|NN color|NN or|CC texture|NN tile|NN and|CC pattern|NN origin|NN .|. 
One|PRP would|MD like|VB to|TO set|VB the|DT visible|JJ size|NN according|VBG to|TO the|DT expression|NN being|VBG displayed|VBN ,|, and|CC to|TO be|VB sent|VBN a|DT message|NN when|WRB relevant|JJ parameters|NNS are|VBP changed|VBN .|. 
How|WRB can|MD CSS|NNP based|VBD style|NN sheets|NNS influence|VBP the|DT style|NN properties|NNS used|VBN within|IN plugins|NNS ?|. 
Dave|NNP would|MD like|VB the|DT math-erb|JJ to|TO put|VB pressure|NN on|IN browser|NN vendors|NNS to|TO fix|VB these|DT problems|NNS .|. 

Action|NNP :|: Neil|NNP to|TO investigate|VB Netscape|NNP Navigator|NNP 3.0|CD plug-in|JJ SDK|NNP to|TO see|VB what|WP improvements|NNS have|VBP been|VBN made|VBN to|TO the|DT api|NN .|. 

One|CD short|JJ term|NN solution|NN would|MD be|VB to|TO add|VB parameters|NNS to|TO the|DT math|NN tags|NNS to|TO specify|VB the|DT context|NN in|IN which|WDT the|DT elements|NNS occur|VBP ,|, e.g.|NN <|NN h|NN 1|CD >|NN ,|, or|CC .|. 
The|DT control|NN panel|NN for|IN the|DT html-math|JJ plug-in|JJ would|MD allow|VB the|DT user|NN to|TO set|VB the|DT font|NN size|NN to|TO be|VB used|VBN in|IN these|DT contexts|NNS .|. 

We|PRP discussed|VBD ideas|NNS for|IN folding|VBG and|CC unfolding|VBG expressions|NNS .|. 
One|CD idea|NN is|VBZ to|TO allow|VB the|DT author|NN to|TO name|VB a|DT subexpression|NN and|CC then|RB to|TO use|VB that|DT name|NN in|IN place|NN of|IN further|JJ occurrences|NNS of|IN that|DT subexpression|NN .|. 
When|WRB folded|VBD the|DT given|JJ name|NN would|MD be|VB shown|VBN in|IN place|NN of|IN the|DT subexpression|NN itself|PRP .|. 
The|DT scope|NN for|IN such|JJ definitions|NNS should|MD n't|RB be|VB resticted|JJ to|TO a|DT single|JJ math|NN element|NN .|. 
This|DT could|MD be|VB supported|VBN via|IN SGML|NNP tags|NNS and|CC attributes|VBZ .|. 

Bruce|NNP talked|VBD through|IN the|DT case|NN where|WRB names|NNS for|IN subexpressions|NNS are|VBP generated|VBN automatically|RB at|IN browse-time|JJ .|. 
This|DT does|VBZ n't|RB require|VB any|DT special|JJ markup|NN ,|, although|IN the|DT ability|NN to|TO give|VB the|DT same|JJ name|NN to|TO common|JJ subexpressions|NNS will|MD depend|VB on|IN the|DT ability|NN to|TO recognize|VB that|IN these|DT subexpressions|NNS are|VBP in|IN fact|NN semantically|RB identical|JJ .|. 
In|IN a|DT previous|JJ discussion|NN Raman|NNP pointed|VBD out|RP that|IN it|PRP would|MD be|VB helpful|JJ if|IN the|DT user|NN is|VBZ allowed|VBN to|TO set|VB the|DT name|NN of|IN subexpressions|NNS as|IN this|DT makes|VBZ it|PRP easier|JJR to|TO remember|VB (|( important|JJ for|IN speech-base|JJ browsers|NNS )|) .|.
