In original SPARQL the syntax was
[19] OffsetClause ::= 'OFFSET' INTEGER
and I did not extend it to something like
[19*] OffsetClause ::= 'OFFSET' expression
because in that time I was unable to efficiently prohibit bad things
like an offset expression that depends on result values. You're the
first who ask about the extension and it can be implemented now, so
expressions will be permitted in the next version. Chances are that you
can get a patch even before that if you specify the exact version you
want to see patched.
