An obvious workaround has just dawned on me after sending this email.

If global_adapter doesn't explicitly get the "adapts" value from the
factory, I must provide it explicitly myself.

So if I do the following, my adapters are registered and the validations

> grok.global_adapter(ProcurementExplanationValidator,
> adapts=ProcurementExplanationValidator.__component_adapts__)

> grok.global_adapter(UniquenessValidator,
> adapts=UniquenessValidator.__component_adapts__)
It however *feels* wrong :D

Is there a better, more elegant way of doing this? I'd still like to
know how global_adapter is now supposed to get the "adapts" parameter it
it's not explicitly passed in.

Also, if the docstring of global_adapter says that "adapts" is gotten
from the annotation, but it isn't, then I guess that line needs to be
removed or the intention cleared up.
