field
and selector
<!ELEMENT field (%XPathExpr;)> <!ELEMENT selector (%XPathExpr;)>
These are the only #PCDATA
content and hence un-annotatable elements in our vocabulary. I propose to
change these as follows:
<!ELEMENT field (annotation?)> <!ATTLIST field xpath %XPathExpr; #REQUIRED> <!ELEMENT selector (annotation?)> <!ATTLIST selector xpath %XPathExpr; #REQUIRED>
