This is an extra data area for ALL Text fields, but is only needed for
Month parsing.
I think a separate class is needed.

-1
AFAICT, this will enable incorrect matching of text fields that are
not supposed to be case-blind.
Also, the case-blind matching is not disabled at the end of the
section, so can affect later matches.
Using a separate class for case-blind matching will fix the first
issue, and will avoid creating duplicate data unnecessarily.

Need more tests to show that the parsing of other case-significant
dates is not affected.
