Purpose: Allow the contained schema resolver to resolve a schema based on a given namespace and schema location, and return either the resolved schema source or null, depending on whether the schema had been processed previously.

Responsibilities:

  • Allow the contained schema resolver to return the referenced Schema given the source schema and namespace and schemaLocation values from an import or include
  • Keep track of previously processed schemas to avoid multiple processing and infinite looping
