$Id: wpsGetCapabilities.xsd 2005-09-16 $ This XML Schema Document encodes the WPS GetCapabilities operation response. Copyright (c) Open Geospatial Consortium (2005). XML encoded GDAS GetCapabilities operation response. This document provides clients with service metadata about a specific service instance, including metadata about the tightly-coupled data served. If the server does not implement the updateSequence parameter, the server shall always return the complete Capabilities document, without the updateSequence parameter. When the server implements the updateSequence parameter and the GetCapabilities operation request included the updateSequence parameter with the current value, the server shall return this element with only the "version" and "updateSequence" attributes. Otherwise, all optional elements shall be included or not depending on the actual value of the Sections parameter in the GetCapabilities operation request.
