Is there a glossary of Word .docx XML tags?

I'm trying to create a parser to find the tracked changes and author of a Word .docx file...

I found the document.xml but there are so many tags! Is there a glossary somewhere to what all those tags stand for?

I'd like to avoid brute forcing my way through this if possible.

Solution

"w:ins" denotes what was inserted when trackedchanges are enabled.
"w:del" denotes what was deleted when  trackedchanges are enabled.
"w:commentRangeStart" denotes the start of a comment
"w:commentRangeEnd" denotes the end of the comment.

All text are found inside 
"w:t" tags.
