telephoneNumberSubstringsMatch

Compares an assertion of Substring Assertion syntax to a value whose syntax is an ASN.1 PrintableString representing a telephone number.

The rule evaluates to TRUE if and only if:

. The prepared substrings in the assertion value match disjoint portions of the prepared attribute value string in the order they occur in the attribute value.

. An initial substring in the assertion value, if present, matches the beginning of the attribute value string.

. A final substring in the assertion value, if present, matches the end of the attribute value string.

Strings match when their characters correspond at each code point. For the comparison, characters are case folded, and only telephoneNumber insignificant white space handling is applied.
