There is a bug in Xerces 2.6.x which causes the external schema location properties to be ignored if the values of features/properties do not change between parses. This has been fixed for a while now in CVS.
Without a schema location another way to locate your schema is with an entity resolver. The entity resolvers in XNI and DOM Level 3 will both receive the schema's target namespace (if it has one). If the location of the schema varies you may want to use XML Catalogs [1].
