mnot’s Web log: Are Namespaces (and mU) Necessary?
It’s become axiomatic in some circles — especially in WS-* land, as well as in many other uses of XML — that the preferred (or only) means of offering extensibility is through URI-based namespaces, along with a flag to tell consumers when an extension needs to be understood (a.k.a. mustUnderstand).
The reasoning is that extensibility should be as easy as possible. By leveraging one registry — DNS — you can use URIs to allow anyone to create your own uniquely identified vocabulary, without any overhead of co-ordination.
This is often contrasted (and deemed superior) to the approach of the IETF, which uses IANA to manage many a namespace, requiring prospective registrants to jump through a variety of hoops to get in.
For those unaware, I am one who preaches to anyone willing to listen, or not listen for that matter, that without XML Namespaces, extensibility is a pipe dream. As such, why am I now suggesting this is no longer the case?
