I usually use:

  <...
    tal:define="templateId	template/id;"
    tal:replace="... templateId ..."

i.e. introduce an auxiliary variable definition.

But the "path" function will do the same effect "path('template/id')".

When you resolve "template/id" (or other path expressions) yourself,
you need to know lots of things. Usually, I try to avoid this road.
