Service URN Labels Created 2007-08-22 Last Updated 2008-01-04 Note The policy for adding top-level service labels is 'Standards Action'. The policy for assigning labels to sub-services may differ for each top-level service designation and MUST be defined by the document describing the top-level service. To allow use within the constraints of S-NAPTR [ref], all top-level service names MUST NOT exceed 27 characters. This registry is also available in XML and plain text formats.
