In that particular instance of xml you have multiple attributes, so the
pattern match would need to be something along the lines of:

    [#xmlAttribute{name=kickoff, value=Kickoff}|_] = Attribs,

but be aware this way depends on the kickoff attribute being first in the
element so its still pretty fragile.
