Mixing Update and Non-Update Features
The writer will accept groups of features where some of the features have an update mode specified, and some do not. In this situation, the writer will create a <NetworkLinkControl> element, and a <Document> element. The inclusion of a <Document> element will replace the result of the previous NetworkLink request, so it is important to ensure that the update mode and targetHref are appropriately.
In instances where a folder hierarchy contains Folders and Child features with a mix of update and non-update features, the entire hierarchy will be assumed to have an update mode of “create”, and will be added to the NetworkLinkControl accordingly.
