XUpdateResolver component parameter
The XUpdateResolver component has one authoring parameter, the Boolean
includeDeltaPacketInfo
includes additional information that can be used by an external data source to generate results
that can be sent back to your application. This information includes a unique transaction and
operation ID that is used internally by the data set.
Note: The additional information that is included in the update packet invalidates the XUpdate. You
would choose to add this information only if you were going to store it in a server object and use it to
generate a result packet. In this scenario, your server object would pull the information out of the
update packet for it s own needs and then pass on the (now valid) XUpdate to the database.
The following is an example of an XML update packet when the
parameter is set to
<xupdate:modifications version="1.0" xmlns:xupdate="http://www.xmldb.org/
xupdate">
<xupdate:remove select="/datapacket/row[@id='100']"/>
</xupdate:modifications>

Note: You may need to create a virtual schema for your XML file if you want to access a
subelement of the array that you are binding to the data set. For more information, see "Virtual
