I've tried \w{2}-\d{2}-\d{3}-\d{2}-\w(2) to enforce NW-03-042-12-W4 for a Legal Land Description.
Problems:
1) The first two characters must always be letters, not numbers. This allows either or.
2) Enforcing the dashes appears to stop me from copy/past from scanned doc to metadata field.
3) The last spot is sometimes only one digit (ie, just a four, not W4) but this enforces two spots to be filled.
Any suggestions on what I should change in the Constraint pattern?
Thx, Connie
