Namespace for our Components

I believe that our components should be in the same namespace as the
pipeline
document.  That would mean that the author would be required to declare a
prefix for the pipeline document's namespace and then use that in the
component step type.

For example:

  <p:step name="xform" type="p:xslt"> ...</p:step>

I don't remember if we decided this or not... but, seems like our
specification
should say the explicitly when we enumerate the components we define.
