oslc.where syntax differs from Lyo reference implementation

https://open-services.net/bin/view/Main/OSLCCoreSpecQuery description of the syntax of oslc.where only supports:

value ::= uri_ref_esc | literal_value
uri_ref_esc ::= /* an angle bracket-delimited URI reference in which > and \ are -escaped. */

However, when I plaigerised the Antlr definition of this from Lyo, I found it also accepted prefixed names. For example, the following was supported:

oslc.where=dcterms:creator=jtsuser:John

providing that the prefix jtsuser was defined. This seems useful, so should we adopt that in the spec?
