Apparent bug with the XSElementDecl::getAnnotations() API
Can someone explain why this happens:
In the ebXML schemas there a lot of annotations in this style:
<xsd:element ref="cbc:Note" minOccurs="0" maxOccurs="1">
<xsd:annotation>
<xsd:documentation>
<ccts:Component>
<ccts:ComponentType>BBIE</ccts:ComponentType>
<ccts:DictionaryEntryName>Order. Note.
Text</ccts:DictionaryEntryName>
<ccts:Definition>contains any free form text pertinent to
the entire document or to the document message itself. This element may
contain notes or any other similar information that is not contained
explicitly in another structure.</ccts:Definition>
<ccts:Cardinality>0..1</ccts:Cardinality>
<ccts:ObjectClass>Order</ccts:ObjectClass>
<ccts:PropertyTerm>Note</ccts:PropertyTerm>
<ccts:RepresentationTerm>Text</ccts:RepresentationTerm>
<ccts:DataType>Text. Type</ccts:DataType>
</ccts:Component>
</xsd:documentation>
</xsd:annotation>
</xsd:element>
This element is part of a sequence particle of a complexType. The ref'd
element type does not have any annotation element, but here an
annotation is added on. In all similar cases the
XSElementDecl::getAnnotation() does not retrieve any XSAnnotation, even
though, as you plainly see, it's right there.
Just FYI, I get the XSElementDecl from the XSParticle.
So what's the issue here, and what can I do to get the annotation?
Thanks,

Hi Elisha,
did you try activating
http://apache.org/xml/features/validate-annotations feature?
Cheers,
Axel

Hi Neil,
Thanks for the response. Well, I'll be sure the add my 5 cents on the
XML Schema comments mailing list. By the way, since I'm not sure which
list that is, do you have the correct email address for it just so I can
be sure I'm posting to where you recommend?
On this note of posting to the schema comments list, I do have another
question that is sure to annoy you ~:) Many weeks ago I asked several
times about Xerces not treating model group instances inside of
compleType definitions as a definable type, rather the type information
becomes *invisible* at that point, and you said well, that's how the
Xerces team interprets that standard. And it would appear that other
implementors of the schema object model interpret that point
differently, notably, Microsoft in their .NET .Xml.SchemaModel (or
whatever namespace it may be) schema parser/object model treat it as a
defined type even at that point. So whomever is *correct* here (both
versions apparently at this point), doesn't it seem that this is also a
fine point that needs to be made more abundantly clear so there is more
*agreement/conformity* among implementations?
The main point for me, as a lowly developer, is that I really detest the
idea of having/needing to support more than one implementation because
they interpret the standard differently! If every *major*
implementation interprets the standard similarly it sure makes life
easier.
What say you?

Hi Elisha,
Hate to be the bearer of bad news, but this is a recognized problem. The
problem doesn't, however, lie with Xerces-C's implementation (Xerces-J
does the same thing); the designers of XML Schema forgot to leave a place
in any component where such annotations could be hung off of. Note that
the XSElementDeclaration isn't an appropriate place, since it's the
declaration, and is shared among all references (as well as at the global
level).
I believe there are plans to fix this for XML Schema 1.1 (e-mail the
Schema comments list if you wish to support that idea).
Cheers,
Neil
