IntegerFirstComponentMatch is an EQUALITY MatchingRule compares an assertion value of the Integer syntax to an Attribute Value of a syntax (e.g., the DIT Structure Rule Description syntax) whose corresponding ASN.1 type is a SEQUENCE with a mandatory first component of the INTEGER ASN.1 type.
that the assertion syntax of this matching rule differs from the attribute syntax of attributes for which this is the equality matching rule.
IntegerFirstComponentMatch evaluates to TRUE if and only if the assertion value and the first component of the attribute value are the same integer value.
