trying this out as triples, because that's where the proof of the 
pudding always is:

X bf:heldBy _:b1 .     //the subject X is held some by thing identified 
by _:b1 .
_:b1 a bf:Organization .     //_:b1 is of type "Organization" .
_:b1 rdfs:label "DLC" .     //the display label for _:b1 is "DLC"
_:b1 bf:hasHoldingOrganization 
<> .     //_:b1, which is 
of type Organization, hasHoldingOrganization 

Putting this again in words:

Some thing (X) is held by some other thing (_:b1). The thing _:b1 is an 
organization as defined by BIBFRAME. The display label for the 
organization is "DLC". The organization "_:b1" has a holding 
organization with an LOC IRI.

This is what Jeff said, I just find it easier to see it when 
triple-ized. If the domain of bf:hasHoldingOrganization is bf:Item, then 
this has declared the bf:Organization "_:b1" to also be an item. In any 
case, it makes no sense that the organization has a holding 
organization. It looks like the correct set of triples would be more like:

X bf:heldBy _:b1 .
_:b1 a bf:Organization .
_:b1 rdfs:label "DLC" .
X bf:hasHoldingOrganization 
<> .

Leaving us, of course, still with the question of organizations vs. 
authorities for organizations.
