Under normal circumstances I would, but I don't have my css in a file. It
gets pulled from a database and stashed in the session. All the header
contributer classes and resource references assume there's a file somewhere
with this info. But in my case there is not.
And, even id I did stuff this data into a file it still wouldn't fix my
problem, because the customer defined css needs to override everything else
with the same css selector. If another component added a header contributor
afterwards that would not be the case.
