Good point.  That's another reason for having as much syntax
handling functions available at the client side as possible/
convenient.  I'm maintaining a "smart" (ah, ah, ...) client 
that populates a DS which started with 1.2.X and grew up with
2.0.X; I faced many syntax issues mostly in a naive way as soon 
as they came up but now I'd like to turn in into a really smart
(as much as I can, of course ;) client by making it check the
schema at the server level, yes, by using the ldap_schema.h
stuff.  But, as soon as I know the syntax of an attribute, I'd
like to use the same (or something very close to the) function
the server is likely to use to check the syntax of my data.

One thing we could do is have functions that deal with 
validation/prettying/normalization into the client library, 
using a schema handler if available or failing if no schema 
knowledge is present.  Then we need an API function that gathers 
(partial) schema information from a target server (or from each 
entry's subschema, or from any standard source, even, say, by 
directly parsing the schema files or so).

I understand there's still the need of some wit from the user 
to collect the appropriate schema info for the purpose.

Ando.
