wsdl test files and licensing

[Michael Albinus]

Hi,

the soap-client people have written a test suite shich is obviously
useful. I would like to merge it into Emacs. This will take time,
because before this happens it shall use ert for running the tests. But
that's another story.

As test data, there are several *.wsdl files as well as soap request
examples (these are *.xml files). All of them are not licensed, except
Debbugs.wsdl taken from the GNU ELPA debbugs package.

Would it be necessary to bring all those files under GPLv3? As said, I
regard them as test data.

Best regards, Michael.
