<documentation>Ordered list of one or more coverages to be added, modified, or deleted, in the specified sequence. Each coverage with its metadata shall be referenced by one wcst:Coverage element within this ManifestType. Each new or modified coverage provided to a WCS server shall include all the metadata needed to populate one CoverageDescription object, as specified in Subclause 9.3 with the exception of the metadata that is specific to a specific server. If the WCS offers CoverageSummary elements, each new or modified coverage shall also include all the metadata needed to populate one or more CoverageSummary objects, as specified in Subclause 8.3.3 with the exception of the metadata that is specific to a specific server. In addition, each new unrectified but georeferenced coverage (image) shall include the georeferencing coordinate Transformation(s). The coverage data is normally referenced remotely, but can be included in the Transaction request message. </documentation>

When this parameter is included, this operation shall be executed asynchronously by the server. In that case, the server shall return an operation acknowledgement to the client immediately following operation acceptance. When operation execution is later completed, the (normal or exception) operation response shall be sent by the server to the response handler referenced by this parameter value. </documentation>
