Merges adjacent <w:ins> elements from the same author into a single element.

Rules:
- Only merges w:ins with w:ins, w:del with w:del (same element type)
- Only merges if same author (ignores timestamp differences)
- Only merges if truly adjacent (only whitespace between them)

Command line tool to validate Office document XML files against XSD schemas and tracked changes.

Auto-repair fixes:
- paraId/durableId values that exceed OOXML limits
