13.2.1 GetCapabilities KVP Binding
This KVP binding is a realization of the conceptual model of the GetCapabilities operation as defined in Subclause 8.1. In general, all requirements defined for the conceptual model of the
GetCapabilities operation apply for its realization as a KVP binding.
Example 30 To request a Capabilities document, a client can issue the following GetCapabilities operation
request encoded as KVP: http:hostname:portpath?service=SOSrequest=GetCapabilitiesAcceptVersions

13.2.2 DescribeSensor KVP Binding
This KVP binding is a realization of the conceptual model of the DescribeSensor operation as defined in Subclause 8.2. In general, all requirements defined for the conceptual model of the
This parameter shall specify the mappings of the set of XML prefixes that occur in the valueReference
to their respective XML namespace URIs. The format shall be
xmlnsprefix,namespace_uri . Multiple namespaces shall be bound
by specifying a comma separated list of xmlns values. Note that the value of the
namespaces parameter is URL-encoded by default Requirement 107.
