another question that pops up is the following: in the documentation, we make a split between userguide (supported) and devguide (not supported). so advanced jpdl properties are not documented in the userguide until they are stable. but the xsd schema *must* contain all those details. as otherwise the jpdl file won't parse in advanced users use unsupported properties. i don't see any other (practical) way then to explicitely document that the xsd might declare more properties. and that only the properties and constructs described in the userguide are supported/stable. is that a reasonable way forward ?
