+This chapter describes how to extend the user schema used by

The first section, {{SECT:Distributed Schema Files}} details optional
schema definitions provided in the distribution and where to obtain
other definitions.
H3: Object Identifiers
-Each schema element is identified by a globally unique
-{{TERM[expand]OID}} (OID). OIDs are also used to identify
-other objects.
-They are commonly found in protocols described by {{TERM:ASN.1}}. In

particular, they are heavily used by the {{TERM[expand]SNMP}} (SNMP).
-As OIDs are hierarchical, your organization
