My *guess* is that soap/wsdlDriver is being overzealous with a camelCase
naming convention and automatically converts all the methods to match
that convention.  Arguably a bug, or a feature.  I don't see it
documented either way in the source.  In fact, I don't see any
documentation at all in the source. :(
