Title: Re: [ubl] Discussion of substitution groups
Of course, the version attribute of the
schema
is useless in this regard, as would be
annotations
for CCTS which, too, are only held in the
schema.
Neither can be referenced in the instance,
only,
correct me if I'm wrong, the namespace and
the
schemaLocation (which could be vague)
can
appear in the instance to identify a schema
or
an identifier within the schema in a
well-known,
standard way. Creating a BIE so that
something
else in instances does the same job, or worse,
putting
that data into another document separate from
the
instance, IMHO just moves the version data to
somewhere
far less well-known, far less
established.
Besides, I though it was intended that UBL
supports
uses which are independant of ebXML,
so forcing
use of CCTS-aware registries seems contrary to
that
(if that is the alternative being offered to XSD
derivation).
Likewise, adopting approaches as alternatives
to
straightforward (though complex) uses of XSD
seems
contrary to another NDR first principle of
UBL.
Steve
I doubt even more whether
the version attribute could do the job. I
doubt
more still that it could be done with a UBL
BIE
for version.
11. I hope nobody suggests that the
version
annotation in the schema be used !!
