myTypeInstance.selectPath(XPathExpressionString) will do that.
No it will not. Instances of schema components in XMLBeans are instances of
classes that implement the interface org.apache.xmlbeans.SchemaType: the
giveaway here is that SchemaType has a super-interface called
SchemaComponent. Neither of these interfaces specify a selectPath method.
selectPath is a method of XmlObject, and only provides access to instance
data, not metadata from the XSD that was used to generate the XMLBeans API.
The current XPath schema is available at http://www.w3.org/TR/xpath/ . It
has not changed since November 1999. It makes no reference to XML schemas at
all: at that time the XML schema specification was only in its third working
draft, and was not yet a standard.
In principle, I could build an XMLBeans interface from the Schema for
Schemas at http://www.w3.org/2001/XMLSchema.xsd, and use that in combination
with the original XSD files (assuming that they are available in all cases).
If you re-read my original question, you will see that I was (in effect)
asking if the metadata that I am after are preserved in the API, so that I
could avoid doing that.

Try using the XMLBeans XQuery/XPath API features.
It seems to me that you have not understood my question. I am not asking how to
retrieve data
from an XML document. I am asking whether certain information from an XML
schema is available
from the API that XMLBeans generates from that schema.
Does anyone have an answer for my original question, or have I found an area
where XMLBeans
support for XML schema is incomplete?
Regards,
Peter.

Dear all,
I have been trying to figure out how to get the value of the "id"
attribute
of a schema
component, but have got nowhere. Can anyone help?
Slightly more explicitly: if my XSD contains a type definition like
this:
<complexType name="MyType" id="some_identifier_or_other">
...
</complexType>
and I have an instance of this type "myTypeInstance", is there some
way that
I can access the
value of "id" by using "myTypeInstance.SchemaType()", or otherwise?
Regards,
Peter.
