I understood that the FIG element could contain overlays, a caption, some
body text, and(recently added) a credit.
Like this:
<FIG SRC="url"><CAPTION>Figure 1: something</CAPTION>
<P>Hello, you can't see my pretty picture</P>
</FIG>
Looking at the DTD (Draft: Mon 13-Mar-95 09:51:25) I see:
<!ELEMENT FIG - - (OVERLAY*, CAPTION?, %body.content;, CREDIT?) -(FIG|IMG)>
which (and I could well be wrong) I take to mean FIG is a container and
can contain (0 or more) OVERLAY, (an optional) CAPTION, a required
body.content (ie marked up text, roughly?) and (an optional) CREDIT.
Is that right?
Looking at <http://www.hpl.hp.co.uk/people/dsr/html/figures.html> this is also
the impression I get.
However, attempting to check some HTML 3 gives a different story:
sgmls: SGML error at figures.html3, line 10 at ">":
FIG end-tag implied by CAPTION start-tag; not minimizable
sgmls: SGML error at figures.html3, line 10 at ">":
Out-of-context CAPTION start-tag ended HTML document element (and parse)
Huh? I don't understand this and I don't understand how SGMLS gets this from
the DTD. If some kind soul could explain it to me, I would be grateful.
Looking for an example to copy, I took the one on Dave's page cited above
and wrapped it up with suitable doctype and so on, like this:
<!DOCTYPE HTML PUBLIC "-//W3O//DTD W3 HTML 3.0//EN//">
<html><head><title>Tester</title></head>
<body><h1>Tester</h1>
<FIG HREF="nicodamus.jpeg">
<CAPTION>Ground dweller: <I>Nicodamus bicolor</I>
builds silk snares</CAPTION>
<P>A small hairy spider light fleshy red in color with a brown abdomen.
<CREDIT>J. A. L. Cooke/OSF</CREDIT>
</FIG>
</body></html>
This gives the following errors when checked against the
(Draft: Wed 01-Mar-95 09:08:15) version of the DTD (old, I know. I shall
come back to that)

cguhpc [87]:
Right, Dave's example had HREF not SRC, ok slip of the keyboard I expect. But
again it appears to be saying that you can't have a CAPTION inside a FIG.
Why?
Ah yes, the Draft: Mon 13-Mar-95 09:51:25 DTD gives some extra errors.
Clues, people?

For those not familiar with html-check, it is a Mark Gaither/Dan Connolly
production which goes:
