Yep

The above would be useful if you don't simply want the value of the
attribute, but you want to do further processing based on the attribute
value. You could turn the attribute into an element and apply templates of
other nodes inside it, for example.

"children" here refers to just the child element nodes. The attribute nodes
are not children of the element. See also the recent thread on "Matching
attributes with @".
