So they are going to use different terminology? The PML structure and semantics are already defined in the PMLCore and other XSD schema. Would not be suprised with a rev of the schema, but a new schema would be rather traumatic. Perhaps they have loosed up the spec so that an epc-is can push out arbitrary xml? But more importantly push it out to what? What is querying and how is it querying? I have my fingers crossed that the XQuery language will be the query language they spec. When can we expect to see the new specs? John 2004-10-08 at 12:26, Somen Mondal wrote: > Hi Guys, > > Just received some information from Michael (VeriSign), here's the scoop on > PML.
