It has also been noted in the JDOM thread that XSD 1.0 is silent on the
question of what the [prefix] of the new attribute should be - see section

It has also been pointed out that the Infoset specification (unlike XDM) does
allow "synthetic infosets" to be inconsistent, for example by having an
attribute that is in a namespace but has no prefix in its name. However, I
think it is undesirable that a schema processor should generate an inconsistent
Infoset, as the history of this JDOM bug illustrates.

One other observation: if we add the rule that in the absence of a namespace
binding, the schema processor should invent a prefix, then we should also say
that it should construct a namespace information item that binds that prefix to
the target namespace.
