What's the new "baseFile" parameter that's added to com.intellij.xml.XmlSchemaProvider#getSchema()?

context of the schema request (module is not enough sometimes :)

1) So, when "foo.xml" references "schemaA.xsd", and "schemaA.xsd" references "schemaB.xsd", what's the context for "schemaB.xsd": "foo.xml" or "schemaA.xsd"?

2) In addition, is it possible to contribute completion variants for namespaces and schemaLocations? In the case of the spring facet, it's trivial to collect a list of all spring namespaces (through "META-INF/spring.handlers"), as well as a list of all "virtual" schemaLocations (through "META-INF/spring.schemas" - those get resolved by spring at runtime).

1) Context file is the place where particular namespace reference is resolved (thus schemaA.xsd :)
2) no

I meant that 2) could not be done right now, so let start from request :)
