Is there a way in XML to make a tag conditionally empty?  That is, if you
have this declaration:
<!ELEMENT syntax - - (attr)*>
<!ATTLIST syntax TYPE (brief | full) brief>
<!ATTLIST syntax ATTRSET CDATA #IMPLIED>
if the attrset attribute of syntax has a value, could the user type it as:
<syntax attrset="foo"/>
instead of
<syntax attrset="foo">
</syntax>
?
