- check for namespaces when decoding
- merge wordprocessingDrawing into wordprocessingml, this fixes some
issues with cyclic import paths (XML namespaces don't translate to
to valid go namespaces due to this)
These are implied values as they are the defaults in the XSD
for optional attributes/elements. However I've noticed that
I keep running into issues where Mac Excel/Word fail to open
a file unless an optional default is provided.
I'll just add them all to hopefully increase compatibility and
save painful file format debugging sessions later.
