ISSUE-8: Using patterns to constrain numerical types
http://www.w3.org/2005/06/tracker/databinding/issues/8
Raised by: Paul Downey
On product: Basic
"""
Description: Occasionally people define schema that use patterns to
constrain the format of numerical types. For example, specifying a pattern
of /\d{3}/ so that integers are of the form 000, 001, 002 etc. Or
specifying a pattern of /\d+(\.\d+)?e-?\d+/ to ensure that a float number
has the exponent. It is generally difficult for binding tools to generate
numbers that conform to arbitrary patterns such as these, even though it is
valid XSD.
Proposal: Recommend against this practice! Use only the min/max/digits
facets to constrain numerical types.
