[OAI-implementers] Question regarding nameapses in V2.0

[herbert van de sompel]

Curtis,

you are definitely right about this.  generally speaking, the second
occurence of the Namespace URI is redundant.  the reason we nevertheless
include it in the dc-part is to make that part self-contained: if you
extract the dc part from the encapsulating OAI-PMH, it still stands as a
document that can be validated.

I hope this helps.

greetings
