// Rewrites a parsed OOXML part in place, applying the Markup
// Compatibility and Extensibility rules of ISO/IEC 29500 Part 3:
//
// - Elements whose prefix an ancestor's mc:Ignorable declares are
//   removed with their content, except that content matching an
//   mc:ProcessContent declaration is kept (the ignorable tag itself
//   still goes away).
// - Attributes with an ignorable prefix and all attributes in the MCE
//   namespace are removed.
// - mc:AlternateContent, mc:Choice and mc:Fallback tags are removed;
//   the content of mc:Choice is dropped and the content of mc:Fallback
//   is kept. Structural misuse of the MCE elements is reported through
//   the ErrorCapper.
// - In a VML stream the root element must be <xml>, and every element
//   named plain "xml" is treated as ignorable.
