Need strict docx → transitional docx conversion step

[gimsieke]

Attached .docx is saved as “strict docx.” Strict docx is one of the more brainfucked concepts on top of the other ISO/IEC 29500-1-related madness. It was decided that really standards-compliant OOXML files would have the same namespace prefixes, but different namespace URIs. That makes all XML-based processing tools moot.

So we either need a preprocessing step within docx2hub that replaces the namespaces when creating the single tree or a standalone strict→transitional step.

Simply manipulating namespaces in the single tree document may not be enough for cases where we first unzip the docx file, create a single tree and only selectively overwrite some of the unzipped files with manipulated chunks. Then some files in the archive will have xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" while others have xmlns:w="http://purl.oclc.org/ooxml/wordprocessingml/main". This will probably lead to an error when opening the manipulated docx.
