In re-reading the below, after it finally came through, I feel that I
either misspoke or need to work on the characterization.

-- We actually haven't modified the meaning, despite its different
context, in the BIBFRAME universe. We use it to identify the MARC
resource with which it is associated.
But, notably, we're not using the LCCN except for provenance purposes.
In other words, we're not using it to identify BIBFRAME resources or
descriptions. So far, the BIBFRAME resources we've found ourselves
creating (if even temporarily) have been given a new identifier
altogether distinct and unrelated to the LCCN.
So, none of above is to say that identifiers are not being used
differently in different contexts, but that my talk of our use of the
LCCN in the BIBFRAME universe was not technically an example of that.
