1.   Problem and proposed resolution

<!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>
