@AirQuick: I see that you logged several issues related to curly brackets. I found an issue where the compiled test is invalid if //x:context/x:param/@select uses syntax like select="map{'key': 'myvalue'}". Should I log a new issue, or does what I described sound redundant with what's already fixed in #463?

@galtm
Can you log a new issue?
I didn't know the problem you found. If it's already fixed, it's just an incidental result of a certain fix.
Thank you for bringing the problem to attention.
