Typo in relcolspec Reference Entry

[Eliot Kimber <ekimber@contrext.com>]

The relcolspec reference entry says:

"element that points to a non-DITA source" and "element that points to a
DITA source".

The word "source" should "resource" in this context: URIs address
resources, not sources.

Cheers,

E.
