Support ExtensionObjects (external assemblies) when using XML Transform
For performing the more complex transformations, it would be great to be able to add an external assembly dll to the "Transform XML" action (or to the Map artifact itself in the Integration account), and be able to use it inside the XSLT maps. Like ExtensionObjects in BizTalk. Today we use a workaround that performs the transformation inside an Azure Function or API App, but it would be better design-wise to be able to use ExtensionObjects in the action itself. It would also make migrations from BizTalk to Logic Apps easier.
