Re: Scope of document() in XSL

The templates which will be applied to elements of doc2.xml refer at one point to an element of doc1.xml by using "//element".

If the current node is in doc2 then //element selects all the element
nodes in doc2. If you want doc1 then you want
document('doc1.xml')//element

document() itself doesn't have scope, it just returns a set of document
nodes (one in this case) what matters is the definition of a leading /
in XPath which doesn't refer to the main input document but rather to
the root node ancestor of the current node.
