The property name can also contain a modifier at the end preceded by a ‘:’ which specifies the
type of data to store in that property. For example <cust_name:A> specifies that customer name
should contain alphabetic characters, spaces, and punctuation. The modifier may also be used
with ignore-fields (i.e., <*>). If no modifier is provided, any type of characters is assumed. The
set of supported modifiers is described in the following table:
Modifier Description
A Alphabetic characters (A..Z a..z), space, and punctuation (. , : ‘)
are allowed.
D Numeric characters (0..9).
N Alphanumeric characters. This is the union of A and D.
\xhh
\xhh is converted to a character with ASCII value hh (always
two hex digits). Only this character is allowed in the field. This
modifier is only valid for “ignore” type fields.
* Any character is allowed (default if no modifier supplied).
