Pretty much, yeah.  The basic idea is, the application declares
each of the namespaces it's interested in along with their
preferred prefixes.  Then when a document is parsed, element
and attribute names are rewritten to use the application's
namespace prefix bindings.  This gives application authors
the same kind of convenient shorthand that the Namespaces REC
gives document authors.

There are a couple issues like what to do with the original
namespace declarations (keep them?  transform them?  throw
them out?) and namespaces that the application didn't declare,
but those are minor and easily dealt with.

What I tend to use nowadays when I have to handle
namespaced documents is a SAX1-equivalent for parsing,
followed by a "namespace sanitizer" that does the above
transformation, followed by a DOM1-equivalent [*] for
the bulk of the work.  That keeps the places where I 
have to deal with namespace URIs at the edges of the 
process; in the middle I almost never have to worry 
about them.

[*] Equivalent in the sense that element and attribute names
    are atomic strings instead of URI/localname pairs or
    URI/localname/prefix triples, not equivalent in the
    sense of having all the features (mis- and otherwise)
    of DOM Level 1.
