Support REAL syntax and matchingRules without precision loss
------------------------------------------------------------

                 Key: DIRSERVER-1004
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1004
             Project: Directory ApacheDS
          Issue Type: New Feature
          Components: schema
            Reporter: Alex Karasulu
            Priority: Minor
             Fix For: 1.5.2


There is no real data type syntax in LDAP.  Nor are there matchingRules for attributes with
this
syntax.  ASN.1 defines an encoding for REAL data types here:

    http://www.itu.int/ITU-T/studygroups/com17/languages/X.690-0207.pdf

Would really be nice to devise a simple encoding for the base, and mantissa of REAL values

to be able to track them without rounding errors due to their persistence in the directory.
 
There's been a lot of conversation about this topic but no one has actually stepped up 
and done it.  Here's some links to these convos:

    http://www.openldap.org/lists/openldap-bugs/200103/msg00065.html
   
Does anyone think they can take a stab at writing an LDAP syntax description for REAL numbers
and providing the required SyntaxChecker and matchingRules for it as well?
