Validation / intellisense using XSDs with same namespace

[dkus]

Hi,

I have two XSDs with same namespace:

document.a.1.0.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" version="1.0" xmlns="urn:xsd:document.a.1.0" targetNamespace="urn:xsd:document.a.1.0">
  <xs:element name="Document" type="DocumentType"></xs:element>
  <xs:complexType name="DocumentType">
    <xs:sequence>
      <xs:element name="A1" type="xs:string" fixed="1"></xs:element>
      <xs:element name="A2" type="A2Type"></xs:element>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="A2Type">
    <xs:sequence>
      <xs:element name="A3" type="xs:string" fixed="3"></xs:element>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

document.a.1.0.add.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" version="1.0" xmlns="urn:xsd:document.a.1.0" targetNamespace="urn:xsd:document.a.1.0">
  <xs:element name="Document" type="DocumentType"></xs:element>
  <xs:complexType name="DocumentType">
    <xs:sequence>
      <xs:element name="A1" type="xs:string" fixed="2"></xs:element>
      <xs:element name="A2" type="A2Type_2"></xs:element>
    </xs:sequence>
  </xs:complexType>
  <xs:complexType name="A2Type_2">
    <xs:sequence>
      <xs:element name="A3" type="xs:string" fixed="33"></xs:element>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

And I generally use validation using catalog. For this XSD's I have the following entries in catalog.

catalog.xml

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system">
  <system systemId="document.a.1.0.xsd" uri="document.a.1.0.xsd" />
  <system systemId="document.a.1.0.add.xsd" uri="document.a.1.0.add.xsd" />
  <uri name="urn:xsd:document.a.1.0" uri="document.a.1.0.xsd" />
  <uri name="urn:xsd:document.a.1.0" uri="document.a.1.0.add.xsd" />
</catalog>

The validation of the following XML passes in VsCode using this extension (I would say due to order of XSDs in catalog):

<?xml version="1.0" encoding="UTF-8"?>
<p:Document xmlns:p="urn:xsd:document.a.1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <p:A1>1</p:A1>
  <p:A2>
    <p:A3>3</p:A3>
  </p:A2>
</p:Document>

But, this one fails:

<?xml version="1.0" encoding="UTF-8"?>
<p:Document xmlns:p="urn:xsd:document.a.1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <p:A1>2</p:A1>
  <p:A2>
    <p:A3>33</p:A3>
  </p:A2>
</p:Document>

When I do validation in Java code I must choose the correct XSD to validate XML.
The issue may be related to XERCESJ-1130.

Is there a way to do the similar in VsCode, keeping the catalog as-is, but choose correct XSD?
