For LDAP, yes, via the atttribute value syntax.  But...

If you want the directory to restrict values of foo to integer
values 1 to 50, you need to define an ASN.1 type that specifies
that restriction:
        1toFifty ::= INTEGER ( 1 .. 50 )
and than specify which OID refers to that ASN.1:
        ( 1.1.1 DESC 'integer values 1 to 50 )
and then you should register the syntax with IANA, and finally
you need to extend whatever directory servers and clients
you are using to recognize and support this syntax.

In short, some specification and coding is required (at least
at present).
