> Node type evaluation in {{SelectorImpl}} is quite expensive especially for
> things like UUID lookups that produce just a single result and use
> {{nt:base}} as the node type. In such cases the current implementation ends
> up reading and caching the entire set of node types just to determine that
> actually any node matches nt:base.
