XML Output is invalid for items with mod-keys

[spamwax]

If I remember correctly, old versions of Alfred did not support modifier keys with items hence it didn't make sense to support that in an XML-formatted output.
My workflow is run under Early-Access version of Alfred and causes this issue. (I will fix it on my end to take care of special aflred versions).
I know this is a very special case, but just wanted to report it here
