The document at <http://dublincore.org/documents/dcmi-terms/> has a lot 
of references to <http://purl.org/dc/terms/> which includes:

<rdf:Description rdf:about="http://purl.org/dc/terms/">
   <dcterms:title xml:lang="en-US">DCMI Namespace for metadata terms in 
the http://purl.org/dc/terms/ namespace</dcterms:title>
   <rdfs:comment>To comment on this schema, please contact 
dcmifb@dublincore.org.</rdfs:comment>
   <dcterms:publisher xml:lang="en-US">The Dublin Core Metadata 
Initiative</dcterms:publisher>
   <dcterms:modified>2008-01-14</dcterms:modified>
</rdf:Description>

So the "canonical" namespace URI for Dublin Core Terms (usually prefixed 
with dct) seems to be <http://purl.org/dc/terms/>.


The "canonical" namespace URI for the Dublin Core Metadata Element Set 
(usually prefixed with dc) seems to be <http://purl.org/dc/elements/1.1/>

<rdf:Description rdf:about="http://purl.org/dc/elements/1.1/">
   <dcterms:title xml:lang="en-US">DCMI Namespace for the Dublin Core 
Metadata Element Set, Version 1.1</dcterms:title>

It's not used. So, no, we don't need the declaration.
