Translate metadata to field content

[J. Landman Gay]

Thanks for the reply guys, both Hermann and Mark, and Bernd who sent me materials offline. I'll 
be going over these suggestions to see what works best. The file content can be very long 
especially when separated into runs (more than 200,000 runs for an average file) so speed will 
matter since this is headed for a mobile app.

I was surprised to see two things:

1. FormattedStyledText appears nowhere in the dictionary. I didn't know it existed.

2. FormattedStyledText treats some punctuation as a new run, even if it has not changed text 
style. For example, semi-colons are independent runs. Very odd.

I need to do some experimentation and timing tests, but thanks to all for the responses.
