See RFC2252 for examples.  In particular, objectClasses and
attributeTypes are two attributes who's syntax is described using
BNF which have string representations.  Note also labeledURI in
RFC 2079 which has a string syntax which conforms to a
specific BNF.  All of these attributes support multiple values.

The difference here is that former requires the server holding
the values to implement and enforce the definition where the latter
doesn't require the server to implement nor enforce the definition.
There are also differences in how matching rules (and indexing)
are designed and implemented.

In general, the former is preferred for operational attributes
and the latter for user attributes not used by the directory.

RFCs are available from http://www.rfc-editor.org/ and countless
other sites.
