Comment describing your root element URL pointing to the workspace root URL pointing to the algorithm; relative to the workspace root. If appropriate, this location can point to some location within the container Optional URL pointing to a location within the algorithm container. This is e.g. useful to acces tools inside ArcGIS Toolboxes URN referencing the specific container, e.g. urn:n52:wps:algorithmcontainer:arctoolbox:9.3 URN referencing a required processing backend, e.g. urn:n52:wps:gpsystem:arcgis:9.3 A collection of the algorithm parameters The tool's parameters If true, this tool's parameters are indexed through their position as integers. Otherwise, the mapping from the ows:Identifier to the respective LegacyID is done via name strings. The Legacy ID by which the parameters are defined in the Legacy environment. Use legacyIntID for sequential parameters, legacyStrindID for parameters name strings
