Yes it does.
My perl at run-time does not know what the name of the slide/file
is going to be. But it can NAME that filename: it can plant a
tag that will be turned into it. So the perl could return
<A HREF='\REFID{name="Section 2"}'
onmouseover="alert('Read this first')">The Second Section</A>
knowing that it would turn into...
<A HREF='slide0012' onmouseover="alert('Read this first')">The Second Section</A>
or whatever...

So I, of course, want both of these:-)

Indeed.
Perhaps something like:
Any unknown tag "\FOO"
causes PerlPoint to call the function FOO with two arguments:
a hash of the arguments given to the tag, and
the body of the tag.
The string returned by the tag is taken as its expansion.
