Yeah, the DocBook stylesheets are big and come with a vast amount of
XPath
expressions; it sums up.

For me, realizing this fact was a happy day; thinking that
it's just a tiny struct, I naively created/freed the XPath context for
every XPath expression-compilation and -evaluation in my Delphi wrapper.
Reusing the context, poured oil into the machinery.
