Re: Default Attributes and XSD

Yup, as Graydon says there are a couple of ways it could be wired up to run
in a single invocation of Saxon.

However, I am questioning the requirement, "more than one transformation
not allowed". What, your XSD is changing so quickly (or you have so many
XSDs) that you have to be able to run the process with a new XSD every time?

If on the other hand the XSD is relatively stable, a way to do this would
be to run an XSLT to produce your list of values from the schema (once),
then use that values list (expressed in XML or XSLT) as a component within
your XSLT runtime (many times). So the two passes are distinct and loosely
coupled. You are merely giving your XSLT a "look up a default" capability,
then externalizing the declarations in your XSD to support that.

On the other hand, all this might be a good argument for why those defaults
should never have been declared in the DTD (or schema) to begin with.

Cheers, Wendell
