The namespace name is a URI (Uniform Resource Identifier).

URI values can be web address (e.g. http://youdomain.com/...)

• web locations: http://yourdomain.com/...

• URN (names): urn:...

• Or other schemes: scheme:scheme-specific-part

But the processor uses the exact string as the URI value and not URI equivalences:

• http://www.somwhere.com/A

• http://www.somwhere.com/%41
