I've just been writing a piece in HTML and had trouble with
anchors using Dan's 3 DTDs (or my 3in1.dtd derived from them).
The content model for A assumes content
and will not allow an omitted end tag (from html0.dtd).
<!ENTITY % A.content "(%heading|%block|%text)+">
<!ELEMENT A - - %A.content -(A)>
However, the only way an A works properly as a target in Mosaic
is if it is empty (has no end tag). The example given in the doc
(Elements/A.html) is correct in this respect:
<DT><CODE><A NAME="4MvVSWBSRpF84aK">href</CODE>
(However, as NAME will eventually become an ID, the value of NAME
given here, starting with a number, will become dysfunctional,
because IDs must begin with a letter; how about knocking that 4 off
the start of it and any others of the sort?)
So the content model should be changed to:
<!ELEMENT A - O %A.content -(A)>
(that's a capital O, not a zero)
