A recommendation:

• Make a folder called 'schemas'

• Put a OASIS XML Catalog in that directory called 'catalog.xml'.

• Put all your schemata in this directory or subdirectories of this directory.

• Make all your schemaLocation attributes relative to this directory structure.

• Put an entries in the catalog relative to this directory structure for all your namespace names.

The result is a portable directory that anyone can use:

• All the schemas are contained in a parent directory.

• The catalog lists the namespaces contained.

• All the schema documents refer to each other with relative URIs and so the URL starting the schema processing should work without special non-standard handling of the URI values.
