Re: section 2.5 - charles' proposal and Jan's proposal

In the examples which spring to mind this is already covered. The two
mechanism used for incorporating stuff into web pages are elements like
SCRIPT, which need to be parsed somehow, and commented server-side things. 

In a case such as Cold Fusion, which makes use of CFML, a specialised markup
language, an authoring tool which produces it needs to understand it (2.5.1).

The output of Cold Fusion pages is HTML, and should be HTML 4.0 if the
authoring tools or authors follow WCAG.

In the unlikely event that somebody tries to use an authoring tool which does
not understand Cold Fusion to edit a CFML page the tool will be faced with
the choice of throwing out the CFML markup and trying to create a valid HTML
page, in which case it should ask the author, or leaving it in there and not
being able to validate it. There is not much else a tool can do.

In the case of the scripts used by you and I, and languages like php, the
pages are valid HTML, with all the magic done from inside comments. An
authoring tool should not remove the comments anyway, but the document is
always valid HTML already. (Although in a poorly designed language the
scripts might break down if things are shifted around by someone who doesn't
know what they are doing. Again, it isn't something a tool can reasonably be
expected to address)

  authors who are not markup language savvy.
