Re: Formal query about WG role and MathML-FAQ

<juanrgonzaleza@canonicalscience.com> writes in part:

:     <doc>
:     <para>Next is TeX </para>
:     <TeX>1 \over {x+1}^2</TeX>
:     <para>This is other text
:     <br/>
:     This is other text </para>
:     </doc>

I would not recommend mixing TeX and SGML.

One can go this way:

   \begin{document}

   Next is math
   \math{\frac{1}{(x+1)^2}}

   This is other text
   \\
   This is other text 
   \end{document}

or this way, which is equivalent XML:

   <document>
    <par>
    Next is math
     <math>
      <frac><numr>1</numr><denm>(x<plus/>1)<pow>2</pow></denm></frac>
     </math>
    </par>
    <par>This is other text<brk>
     This is other text
    </par>
   </document>

There are extant authoring systems for MathML some of which support
these approaches.  See
http://www.w3.org/Math/Software/mathml_software_cat_authoring.html
(plus several new ones not listed there: Hermes, LaTeXML -- both of
which have links at

converting-tex.htm ['\' used for line continuation] -- and blahtex,
maybe others.
