I just learned that I cannot put a head tag inside a list: although this is valid in XML, it is NOT valid in the HTML. In this case, then, I have decided to use simple p tags, even though technically a head tag would be more accurate.

Also: any time there is a reference that is continued after a page break, it must be made into two references, as this is another instance where HTML does not validate a practice that is acceptable in XML.

That's all for now! L.
