xml-mode and *html*-font-lock-keywords - why?

Adrian, could you elaborate a bit on why it is necessary to put html-font-lock-keywords into effect when one is editing an XML file [1]? Those keywords contain stuff that is plain wrong in XML, such as fontifying stuff inside the <strong> tag in bold. Fontification in psgml is certainly a Very Good Thing, but I think the current approach is not correct. Additionally, psgml-parse.el already has some fontification stuff (not font-lock), and mixing font-lock with it might produce weird side effects. At least my XEmacs behaves pretty unexpectedly when editing HTML files nowadays, try it out like this: 1) Start XEmacs, C-x C-f doesnt_exist.html RET 2) Fill in the document title 3) Note the colours 4) Go down below the <h1> tag, hit TAB 5) Watch the colours change I think this is because psgml's own fontification kicks in when one hits the TAB in the above. Doing M-x font-lock-fontify-buffer RET brings back a consistent state (ie. the one that psgml-html and its font-lock does), but editing the buffer after that again changes the colours. As you already note in [1], this is the first cut and most likely work in progress, but could you give any estimates how/when/if you're planning to continue the work? I'm afraid that we'll start receiving bug reports about this soon... [1] <http://list-archive.xemacs.org/xemacs-patches/200112/msg00169.html> -- \/ille Skyttä ville.skytta at xemacs.org
