The single biggest hurdle for people using XPATH in IDM is not knowing
this one line of information found in the docs:
"The context node is the current operation, unless otherwise specified
in the description of the expression."
This is such an important detail, to have it as a single line, not
called out, bolded or explained is a real issue.
Almost every single issue beginners have with understanding XPATH usage
in IDM (2, 3, 3.5, 3.6, and still in 4) stems from this one item.
This really needs to be made more in your face in the docs.
