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:recordedBySteve 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:recordedBySteven J. Baskauf</dwc:recordedBy> ?
