- Each SchemaInfo should have its own NamespaceScope (pre-populated with the content of the including grammar) instead of pointing to a stack of the NamespaceScope of the topmost grammar (otherwise, if A includes B and then C, C sees the namespace prefixes declared by B)
- SchemaGrammar should not be used to store the transient NamespaceScope objects
- The stack of NamespaceScope is updated by each DOMElement that has attributes declaring new namespace prefixes (XERCESC-1592)
