I assume that you're saying that:
Let there be ordered pairs x,y such that the property dc:creator of x
is y. If each such y is also a dc:contributor to its corresponing x,
then dc:creator should be regarded as a sub-property of
dc:contributor.
To be more serious ;)

Lets have a go at this one
A Creator is "an entity primarily responsible for making the content
of the resource", whereas a contributor is "an entity responsible for
making contributions to the content of the resource".[1] Then
1. A possible interpretation of this that if we have entities making a
content, then these entities will be either either creators or
contributors. What their relation to the content will be is related to
the evenness of the distribution of contributions (measured in quality
of quantity of their work). If it is roughly equal, then all are
creators, if it is unequal then some of them are just contributors.
For instance, if we have 10 persons each contributing 10% of the content,
they should all be regarded as creators. If on the other hand one
single creator does half of the work, and the remaining nine
contributes the rest. We've got one creator and nine contributors.
2. A possible interpretation is that it is not the distribution of
work, but somehow the relative amount work. That is if ten persons
contribute equal amount of work, then they are all contributors. If
they were just two, they would be creators.
3. An equally possible interpretation is if a single entity
contributes all the work needed to create a content, this is
compatible with being responsible for "making contributions to the
content of the resource".
I personally find the third interpretation most appealing. I leave the
following as an exercise to the interested reader.
1. Let
x = Pooh and Pigles find a Heffalump
y1 = Milne, A. A.
y2 = Shepard, Ernest H.
Then: What is the relation between x and, respectively, y1 and y2?
2. Prove that dc:creator isn't a Heffalump.
