Yes, in fact, I use it to copy some Elements and create my own XML. Unfortunately, the XML plugin doesn't support the .importNode method 
.
By the way, I found some bugs (as you already know) and some errors in "built-in" workflows. I don't know how to report this things. For example: the Create Vdc workflow use "amount of cpu" as CpuSpeed.
I don't want to create a "case" because I don't really need assistance.
Is there any "contact form" or something to report this things?
