# caseIgnoreListSubstringsMatch

Compares an assertion value of the Substring Assertion syntax to a value whose syntax is an ASN.1 SEQUENCE OF the DirectoryString type.

The rule evaluates to TRUE if and only if the assertion value matches the concatenated strings of the attribute value, where none of the initial, any, or final substrings match if they span more than one of the original attribute value strings. The match is evaluated according to the `caseIgnoreSubstringsMatch` rule.
