I wondered about that myself sometime ago. And no, query is not implemented.
Its the only missing construct-expression. It may have been left out because
this simplifies certain things. Eg, (current-node) will always be an element
node unless you use query. The style-query-expression can be any expression 
returning a node-list, eg something like

(q-element 'footnote (current-node))

returning all footnote elements within the current node. Note that
(current-node) returns the root of the grove withing the 
style-query-expression.
