Package.from_dict(obj.to_dict()).to_xml() messes up vocab types

[slbayer]

To recreate, do this:

import maec
obj = maec.parse_xml_instance("maec_4.1_examples/package_manual_analysis_example.xml")["api"]
print maec.package.package.Package.from_dict(obj.to_dict()).to_xml().encode('utf8')

(the final encode() is because I'm printing to an ASCII terminal; it isn't going to affect the problem).

In the output, search for BAD_XSI_TYPE, which occurs all over the place.

Thanks for the bug report. This stems from an issue with the use of the is_plain() method in the VocabString python-cybox class. I've added a tracker entry there to evaluate it: CybOXProject/python-cybox#174

Turns out that this issue:

#36

is actually another instance of this one, because I didn't realize that what I was looking at in this other issue was the output of to_xml() produced with the pattern noted here. So in addition to BAD_XSI_TYPE, I see cyboxVocabs:ActionObjectAssociationTypeVocab-1.0 instead of maecVocabs:ActionObjectAssociationTypeVocab-1.0. Sorry for the confusion.
