From my understanding (and after reading the example Bob referred to), the difference is:
[referring to external id]
<dwc:recordedBy rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me" />
[inline text]
<dwc:recordedBy>Steve Baskauf</dwc:recordedBy>
Look right?

Hi Bob - should the same term allow both types of content, or should
there be a different term for each? Does it matter? Should
applications be smart enough to tell the difference and know what to
do with it?
Not really asking what the specification says, but about purity and
wholesomeness of design... :)

Exactly this example is given in
http://web4.w3.org/TR/REC-rdf-syntax/#section-Syntax-property-attributes
so I would find it regrettable if DwC does something somewhere that
makes this substitution impossible or discouraged, or encourages tool
construction that does so, or encourages documention be interpreted in
a way that does so.
Indeed http://rs.tdwg.org/dwc/rdf/dwcterms.rdf defines its type to be
rdf:Property and is silent on any semantics but that. My own
conclusion is that neither the intent or the outcome of the rdf
version of dwcterms discourages what you want, though I suppose the
intent part would be clearer if the documentation also said that a URI
can always be used, but applications are responsible for interpreting
it.

The definition for the Darwin Core term recordedBy
http://rs.tdwg.org/dwc/terms/index.htm#recordedBy
says "A list (concatenated and separated) of names ...". The examples
given are string literals. However, when using this term as a predicate
in RDF, it would seem preferable to use a URI to an RDF representation
of the entity (if one exists) rather than a string literal. For
example, can I use:
<dwc:recordedBy
rdf:resource="http://people.vanderbilt.edu/~steve.baskauf/foaf.rdf#me"/>
rather than
<dwc:recordedBy>Steven J. Baskauf</dwc:recordedBy>
?
