[oXygen-user] Removing or adding two attributes at the same time

[Oxygen XML Editor Support]

Hi Felix,

In addition to Patrik's useful response, just to answer some of your 
original questions:

Indeed, only one operation can be triggered in a certain XPath 
activation context. So besides using the XSLT Operation you could also 
implement a custom Java operation to set both attributes to the current 
element using our API.

A small example configuring an XSLT Operation can be found here:
