sibling order doesn't parse

[pieterbos]

If you write a sibling order before the first occuring attribute, it gets parsed.

If you put one between two attributes, it results in a parse error, or so it seems:

This should now work.

This works (though yet to be implemented in my parser). A lot of thanks for the quick and many fixes!
