Section 7 of this document gives an example of (int=\00\00\00\04) and
shows hot the LDAP URL representation for the same.
The use of "int" seems to indicate here that its an integer attribute
which is being talked about. Its unlikely that an integer syntax
attribute will encoded like this.
Though its not technically incorrect, for better readability sake,
would it be a good idea to choose some other attribute name than "int"
like bin (bin=\00\00\00\04) as in section 7 of
draft-ietf-ldapbis-filter-04.txt.
