The dot is used or usable in any XPath expression
(https://www.w3.org/TR/xpath-31/#dt-dynamic-context) so I would suggest
to rather look at XPath to understand the context item or context node
as otherwise stuff like
   /items/item[cat[. = /categories/cat]]
will not be understood.

That is what the
  current()
function does, I am currently not sure why you first cite it and then
seem to ask for another function doing the job of the current() function.
