This is interesting, and I found it quite by accident. I just opened a
js shell to check the foo.@value syntax thinking that the @value
wouldn't be a valid property name.

$ js
js> f = {}
[object Object]
js> f.@value = 2;
2

Which looks ok, but the first shell I actually tried did this:

$ js
Rhino 1.7 release 1 2008 11 26
js> f = {}
[object Object]
js> f.@value = 2;
js: "<stdin>", line 3: uncaught JavaScript runtime exception:
TypeError: [object Object] is not an xml object.
	at <stdin>:3

It would appear that on my Ubuntu machine the js shell is provided by
Rhino which is what couchdb-lucene uses and the @value is invalid for
normal objects.

Weird...
