I believe the current charter permits > your design without prescribing it. What do others think? While this topic is really closed (see my parallel response), I cannot claim that I understand your line of reasoning here. Grammatical extensions such as from SPARQL 1.0 to 1.1 are "compile-time" changes. What the WG will need to address are "run-time" changes that allow any user to express constraints that are not covered by the collection of predefined shapes. And I don't know SOAP well enough to know what MUST/MAY UNDERSTAND means (and a quick Google search was not informative either). I don't think my proposal was excluding any design, it was just stating a problem. In fact, many people will find the ability to define custom constraints far more important than the use of pre-defined shapes. A standard that does not deliver that extensibility would be a failure. Thanks, Holger
