RE: [Bodington-developers] XML Repository and namespace prefixes

[Colin T. <col...@co...>]

I like option 3, and storing the namespace prefix, presumably separate from
the rest of the element name...
Isn't the SAX parsing a problem for option 2 too?
If I'm understanding what you're saying, parsing (on import?) might not
provide the namespace, so it won't get the URI either will it?

In the example you quoted, is the element name being stored as imsmd:record?
That suggests a problem in parsing i.e. it doesn't understand what a prefix
is (unless it's a quirky Bodington way to store the prefixes).
