Ha! Yes, you found a cute workaround that takes advantage of an
inconsistency in the current spec: cookies are easily accessed by name
using XPath but not the EL. Of course, the technical issues (and whether
we can stomach a simple name-based lookup, in view of these issues) are
the same for both the EL and the XPath variable bindings. Whichever way
the expert group decides, the EL and XPath will almost certainly be
synched with each other by the next release. (That is, they'll either
both have 'cookie' or they both won't.)
