I think I traced down the issue:
I logged the output of the xml import and got back a warning:

"Error: unknown type <qa:ContextInformations>

with the message:

"unparsable content <qa:contextInformations> detected
	line: 6
	column: 8
	nested error: unknown type <qa:ContextInformations>"

When I save my extension “contextInformations” it is written with a lower case first letter but apparently when loading the xml it cant parse this because it is expecting it to be written with capital first letter. I completely searched my code and I never write it with a capital letter. When I do, everything works fine. Is this some kind of convention to be followed? Funny thing is, if I write it with capital first letter in my code and save it to xml, it is written with a lower first letter inside the xml.
