1.0 Introduction

   SLP templates [1] are intended to create a simple encoding of the
   syntactic and semantic conventions for individual service types,
   their attributes, and conventions.  They can easily be generated,
   transmitted, read by humans and parsed by programs, as it is a string
   based syntax with required comments.  Directory schemas serve to
   formalize directory entry structures for use with LDAP [2] These
   directories serve to store information about many types of entities.
   Network services are an example of one such entity.
