Here are some namespace best practices for someone about create their
own markup:

1. Always use a prefix, never change the default namespace.
2. Choose a namespace that will never, ever change - eg don't include
version numbers or dates
3. Avoid using URLs, the globally unique benefit is far outweighed by
the confusion cost
4. Keep it short, XPath 3.0 can include the namespace directly in the xpath
5. Use the standard prefixes for existing namespaces
6. Always declare all the namespaces on the root element

The goal is to help consumers of the xml avoid all the usual pitfalls
around namespaces.  Some potentially controversial ones in there...
