&SecRef-1;Single Source AuthoringSituation WantedWrite a single source file to produce: Finely Typeset PrintConsistent, Valid HTMLand to benefit from: No Need for Intervention Beyond SourceThe Possibility of Other Translations
&SecRef-2;Translating Almost ImpossibleGood Structure a HelpMay Require Human InterventionNeed to Proof Read Twice
&SecRef-3;Translating HTMLReliableBut: No Math in HTML HTML Generally Less Rich Than Nuisances:

&SecRef-7;GELLMUGeneralized Extensible Like MarkUp A markup interface for writing (SGML or) XMLlike notation more succinct than that of XMLExtensible using GELLMU's newcommand with arguments (SGML has no analogue of macros with arguments.)Other metacommand facilities including: (1) documenttype (2) macro

&SecRef-11;Syntactic Differences from Command names (element names) may contain numbersExample: frac23 is a command nameArguments must be delimited with braces or bracketsNo white space between command name and first argument delimiterNo white space between delimiters of successive argumentsBracketed arguments may not be optional

&SecRef-24;Viewing MathMLViewing support for MathML in web pages is not yet widely available The above item can be rendered by: Href="http://www.w3.org/"W3C's Href="http://www.w3.org/Amaya"Amaya: Href="http://math.albany.edu:8000/hammond/gellmu/wprod.html"wprod.html or Href="http://math.albany.edu:8000/hammond/gellmu/wprod.xml"wprod.xmlHref="http://www.mozilla.org/releases/"Mozillas MathML development track: Href="http://math.albany.edu:8000/hammond/gellmu/wprod.xml"wprod.xml (only)With special plugin for MSIE: Href="http://math.albany.edu:8000/hammond/gellmu/wprod.html"wprod.html (only)
&SecRef-25;Generating MathML from articleAd hoc wprod.html was made from GELLMU source: Href="http://math.albany.edu:8000/hammond/gellmu/wprod.glm"wprod.glmThe short iref="gamma-src"article form (slide &LabelRef-gamma-src;) of GELLMU source above could be given automatic translation to MathMLAn automatic translation should go through content MathML and from there to presentation MathMLAn automatic translation would not be under the umbrella of general XML processing
&SecRef-26;Reliable Generation of MathMLReliable translation will require: A substantial nonXML, but XMLaware, parsing of all math zones in a GELLMU source document Occasional math parsing hints from authors in their markup Desirable, sometimes required: Source markup labeling of math symbols Source markup typing of math symbols
&SecRef-27;MathML Generation IssuesWill authors cooperate Will standard web user agents cooperate
&SecRef-28;How Were These Slides Made?There were two sets of slides and, correspondingly, two formatters, one for Href="slidegart.pl"transparencies formatted by the regular program latex and the other for Href="pp4gart.pl"PP4PDF web slides formatted by the program pdflatex using a number of packages including ppower4 by Klaus Guntermann of Darmstadt University of Technology Actually I used a small modification of pp4slide.sty named gpp4slide.sty to make things work with the standard slides document class Both of these work with GELLMU article, and there are slightly different definitions of slide with newcommand in the two
