Peripheral Attributes for \w

[cmahte]

I'm working on tagging a nonscriptural work, but this seems to apply back to scripture the same way.

For Scripture works:

In prior and current USFM, Glossary, Names Index, Maps Index, and Topical Index peripheral matter have historically been built manually as a peripheral with links to scripture embedded.

Instead, I propose formally defining word level attributes {"glo" "ndx" "tdx" and "map"} to be used as index anchors within the \w \w* tag, so that these peripheral tables are not manually maintained but built based on the anchors when the material is published.

Inside of paratext their could easily be a "build/update index" feature within this peripheral books that would do the scans.

This additionally allows building topical/glossary/Names indexes that include links to non-scriptural points in books (links will work without having a scripture reference, including introductory, and other peripheral book locations.
