The decision between an attribute or a new element is still open and
this is one reason to opt for a separate <Subject> and <SubjectSet>
elements. In a separate approach, the <SubjectSet> element can have a
'match' attribute which will only define 'beginswith' at this point.
The content of this new element will be string.
