[pmwiki-users] non conformant XHTML 1.x tags

[Jean DEMARTINI]

The (X)HTML text generated by PmWiki (or some cookbook recipes) is
populated by non conformant XHTML tags.

For example:

each <h1></h1> pair of tags is systematically preceded by
<p class='vspace'> instead of <p class='vspace' />

How is it possible to modify the HTML generator to produce strict XHTML
1.x text ?

Many thanks.
