I hadn't thought of these possibilities, thanks Rick.
This one is fine and legal, but requires the processor (all friendly
processors) to look for namespaces in attribute values. Since attributes
can have colons for many other reasons I suspect this approach will cause
problems. For example:
>and the contextref attribute you suggest, e.g.
This relies on the namespace proposal being adopted for attribute names. I
don't know where that has got to, and its probably confidential to XML-SIG.
I can see its attraction in cases like this.
The namespace allows the pre-colon prefix to be mapped to a schema file,
which could - in turn - contain a reference to the XML-DEV posting(s).
Something like XML:BEHAVIOR would *not* be a good idea because it would be
a different attribute from BEHAVIOR. So if only the BEHAVIOR attribute were
altered (BEHAVIOR="XDEV:BLINK") there would be no formal method of picking
I cannot remember whether PIs can be linked to schema files, i.e. something
