Metacat

Looking at this record in metacat in XML, I noticed that only the root element
has a prefix ("eml:"), and that there isn’t a default namespace URI declared for
elements without prefixes. I’ve looked at a few other records, and so far they
all follow the same pattern.

I tried to see if the records would validate against the eml*.xsd files despite
not having prefixes, but then I ran into bug 2054
(http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2054).
