| Also, if you had a document containing several prefixes for the same
| namespace, you could easily use the localpart and uri, rather than
| the prefix.

| The prefix shouldn't be used except for convenient uniformity from
| input to output, and for the few W3C-sanctioned cases such as XPath
| name tests.

Agreed. The prefix is just a lexical detail, only useful for
roundtripping.
