Hi Craig,
I looked at the jdo_2_0.xsd and changed it the way you described in your
email. I changed the sequences including a list of extensions at the
beginning and at the end into choices. I also added some documentation
enclosed in <xs:annotation><xs:documentation> ...
</xs:documentation></xs:annotation> describing which subelements must
not occur more than once. You find the updated xsd attached. Please have
a look.
I propose to renamed the file to jdo_2_1.xsd and change the version
entry to 2.1, since this will go into the JDO 2.1 Maintenance Release.
What do you think?
Regards Michael
Javadogs,
According to my xsd expert, we're misusing xsd in the published ns/jdo
xsd files, and if we want to preserve the existing semantics we need
to change the xsd and add some code to jdo implementations.
Specifically, if there is not a definite content between the beginning
and ending extension, then the parser is correct to complain. He
suggests that we redefine the xsd to allow a mixture of extension and
other elements. If more restrictions are needed, such as only one
occurrence of datastore-identity, primary-key, and inheritance, then
the implementation needs to enforce this and not depend on the parser.
The implication is that we redefine the xsd for all the elements that
currently allow extension, and put more of the burden on the jdo
implementation to catch errors.
As part of this, I'd be willing to relax the requirement that
extensions occur only at the beginning or at the end of elements. I'll
have a more specific proposal for your review later.
