Exported OpenLDAP schema has syntax errors

If you export a schema to OpenLDAP schema format, you cannot import it to slapd because slaptest fails with:

1. slaptest -f test.conf -F tmp/
   55898c8a drksuewo.schema: line 5 attributetype: Missing closing parenthesis before end of input
   AttributeTypeDescription = "(" whsp
   numericoid whsp ; AttributeType identifier
   [ "NAME" qdescrs ] ; name used in AttributeType
   [ "DESC" qdstring ] ; description
   [ "OBSOLETE" whsp ]
   [ "SUP" woid ] ; derived from this other
   ; AttributeType
   [ "EQUALITY" woid ] ; Matching Rule name
   [ "ORDERING" woid ] ; Matching Rule name
   [ "SUBSTR" woid ] ; Matching Rule name
   [ "SYNTAX" whsp noidlen whsp ] ; see section 4.3
   [ "SINGLE-VALUE" whsp ] ; default multi-valued
   [ "COLLECTIVE" whsp ] ; default not collective
   [ "NO-USER-MODIFICATION" whsp ]; default user modifiable
   [ "USAGE" whsp AttributeUsage ]; default userApplications
   ; userApplications
   ; directoryOperation
   ; distributedOperation
   ; dSAOperation
   whsp ")"
   slaptest: bad configuration directory!

The problem is that the exported schema misses the required whitespace character in front of the closing parenthesis of each attributetype and objectclass element. The fix is easy, just the renderer must be corrected.
