HI Bancroft. I have two points on XER:
First on canonical XER with xmlhstring, I don't see anything about lower or huper case letter for 'a' 'b' 'c' 'd' 'e' and 'f'. The second is a reflexion on Enumerated when we try to transmit a value of the extension. You proposed to send the number instead of "<identifier/>". But there is a little probleme with SEQUENCE OF ENUMERATED In such a value you will have : <T>11<identifier1/>12<identifier2/><T/> How many values do you have ? (4-5-6) As we use the XMLValueList for Enumerated and not SpaceSeparatedList, two values of the extension can be juxtaposed. So we can't use the number for Enumerated. Pierre-Marie.
