Unfortunately not for this particular use case. I am currently in the
process of redesigning a website where the requirement is to have a
text like the one above on every page in the header.

Thanks for pointing me there. I immediately stopped reading after the
stop words "human relations" :)

IMHO rel="controlling" seems to be a bit misleading to me.

Using my previous example:
<p>Part of <a href="http://www.a-inc.com/" rel="controlling">A Inc.</a></p>

I would understand (from the definition of rel-attribute [1]) that B
Ltd. is controlling A Inc. but it should the other way round (or do I
get it wrong?). So a better wording should be used (maybe
"parentgroup" or something like that). Whereas rel="subsidiary" should
be quite clear.

Anyway: A real world example could be [2] where the corporate group
links to its subsidiaries, and the subsidiaries will link back
indicating the reverse relation (this looks like a lot of javascript,
but you will get the idea).

Another example could be [3] for the same use case.

There might be another use case when companies are accredited dealers
of another company (and the other way round) and want to show this
using a microformat. An example could be [4].
