modifyTimestamp doe snot react on searches with wildcards (*), because
there is no SUBSTR matching rule in the definition of the attribute.
It does however react on ordering comparisons (<=) because the attribute
definition contains an ORDERING matching rule.
So, it's being special comes from the matching rules, not from the fact that
it is defined in the code.

I don't know the exact meaning of "gen up", but you may look in
servers/slapd/schema_prep.c starting at about line 330.
They should be also in the schema that the server delivers.
Try to look for "USAGE directoryOperation".
