Comments against TMQL draft dtd. 2007-07-13.
There seems no easy way how to constrain the scope of an predicate
invocation. Is that intentional?
member-of(member: ec, group: cream) @year-1966
member-of(member: ec, group: blind-faith) @year-1969
How can someone constrain, that only the memberships in the scope
"year-1969" should be returned?
member-of(member: $p, group: $g)
would return everything.
IMO it would be nice if the user can constrain the scope of a
member-of[@year-1969](member: $p, group: $g)
Otherwise the user has to fall back to path expressions and cannot use
the (more readable) predicate invocations.
