--------------------------------HREF and Glossaries-----------------------<BR>
This description of glossaries may be obsolete with the introduction
of DICTNAME/CONVENTION, and the mechanics still have to be worked out.
<BR>
<BR>
The syntax is as in Murray's document.  CML makes extensive use of glossaries
via the REL=glossary attribute.  Typical uses of HREF are:
<UL>
<LI><B>External URL:</B> HREF="http://www.dl.ac.uk/CBMT/cml/"
<LI><B>Relative URL:</B> HREF="../myfile.html".  The author is responsible
for maintaining the file structure; the postprocessor might convert this
to an HTML hyperlink, although other mechanisms are obviously possible.
<LI><B>Internal URL:</B> HREF="#mylabel".  The target must be defined by
a NAME attribute (mylabel).  At present this link has no <i>strong</I>
<B>type</B>ing
mechanism; i.e. the tail does not specify what type of object is located
at the far end.  The postprocessor will have latitude here; for example, if
the target identifies an encapsulated diagram, it might be inlined or 
indirected through a hyperlink.  See <A HREF="name.html">the NAME attribute
</A> for XML/CML suggestions.
<LI><B>Glossary</B>: REL=glossary HREF="/cml/crys?cell".  This looks for
the entry <I>cell</I> in the glossary <TT>/cml/crys</TT>.  How it is 
rendered will be at the discretion of the postprocessor (e.g. inlined or
active hyperlink).
</UL>
<P>
NOTE:  REV is also implied and available for all elements, but no
semantics have yet been defined in CML/XML.
</P>
<H1>REL, REV, URN and METHODS are included but rarely used</H1>
