I expect the specification to define conformance requirements for implementations and SPARQL implementations will have to deal with illegal input. This is not uncommon in fact, XML 1.0 for example defines this in detail. I am not sure why it would be useful to allow SPARQL implementations to handle illegal input in different ways but if that is intended, it should be very clear from the draft. -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Weinh.
