I tried it and it works!!!  But it is a mystery what exactly is
saxon:evaluate() doing?

It receives the following argument $container//account/person/@name because
of the concat function.

concat('$container/', $path) where $path is /account/person/@name

Is $container//account/person/@name a valid XPath expression?

I tried looking up the documentation for the saxon:evaluate and
xalan:evaluate() but I couldnt answer the question.

Do I need an extra slash between $container and the $path?
