Is there a chance to serialize an XSDSchema ? I having performance trouble
with XSDSchema instanciation from DOM, and in my case, can be avoided if I
can serialize and XSDSchema.

Rodolfo,

Doing xsdSchema.eResource().save(System.out, null) should serialize your
instance.

Hi everyone.

I'm trying to understand how to use XSD's SubstitutionGroups support. I
understand the XML/Schema construct at a practical level but I'm unclear
about the APIs:

1. ElementDecl.getSubstitutionGroupExclusions
2. ElementDecl.getSubstitutionGroup
3. ElementDecl.getSubstitutionGroupAffiliation

That I want to do is compile a list of substitutions given an abstract
element declaration. I expected to be able to call
elemDecl.getSubstitutionGroup and ave that return all of the
elementDecls that can substitute. But only the element itself is
included. An I out to lunch? Alsi what is an affiliation and an exculsion?

Thanks

Jim,

I'm not sure whether you have lunch in or out. ;-)

Each of these things have Javadoc that point at where the concept is defined in
the spec, so there's no point in repeating that information. I know the spec is
not much fun to read, but it's very precise. The basic idea is that
getSubstitutionGroupAffiliation is a concrete relation that set's up the
substitution group by saying "This element belongs to that element's group".
The getSubstitutionGroupExclusions defines limitations on what kinds of elements
can be in the element's group. And the getSubstitutionGroup returns all the
elements that are directly or indirectly in the group by virtue of the
affiliations.

Were you trying this out with any particular examples in mind?

Thanks for the descriptions - you're spot on. I can *read* the spec but
that doesn't mean I can understand it. If I understand you right this
means the getSubstitutioGroup returns the set of elements that can
substitute for and element while the getSubsitutionGroupAffiliations is
a "back pointer" to the element where this element can substitute.

Actually it turns out the problem I was tracking down was the result of
a bad schema - but pretty understandable.

The author setup a pretty simple substitutionGroup based ona global
element declaration called: fred of type fredType. But, he went on to
attempt to use "fred" by creating a sequence of local elements named
"fred" of type "fredType". "Clearly" the 2 element decls are unrelated
but...
