both are correct.

a) will work with any processor which "knows" what the schema for the XML namespace is (check the documentation for your processor(s) to see if it already "knows" that schema).

b) will work with any processor that honors the schemaLocation **hint**.  Just as with xsi:schemaLocation, this is only a hint and processors are licensed to ignore it.  However, most _general purpose_ processors such as xerces do, in fact, honor it.
