Validating against several .xsd documents

Question

Dear Oracle experts,
I have a problem when I want to validate a xml document against several .xsd schemas. I am using the following constructor of the XSDBuilder:
build(XMLDocument[] schemaDoc, java.net.URL baseurl)
Build XMLSchema from Array of XML documents
to build a XMLSchema for the validation:
XMLSchema schemadoc = (XMLSchema)builder.build(xsdArray1, baseURL);
But for some reason the XSDbuilder does not seem to like my array of XMLDocuments
XMLDocument[] xsdArray1 = { XSDDocument1, XSDDocument2, XSDDocument3 };
and it throws an oracle.xml.parser.schema.XSDException.
There is nothing wrong with the XMLDocuments in the array, so I do not understand why the exception is thrown.
Is there any other approach to validate against several .xsd schemas, or do you have some tips about what could be wrong?
Thanks!

Yes they are. That's the strange thing. I can't see anything wrong with the input array.
Here is my code:
parser1.parse(xsdURL1);
// Obtain the xsd-XMLDocuments:
parser1.parse(xsdURL1);
parser2.parse(xsdURL2);
XMLDocument XSDDocument1 = parser1.getDocument();
XMLDocument XSDDocument2 = parser2.getDocument();     
XMLDocument[] xsdArray = { XSDDocument1, XSDDocument2 };
XMLSchema schemadoc = new XMLSchema();
schemadoc=(XMLSchema)builder.build(xsdArray, baseURL1);
Any suggestions of what could be wrong?
Thanks again!
