There's no direct relationship between the form of the XPath expression used in a select attribute and the form of an XSLT pattern used to match the nodes. a node might be selected by select="foo" or select="parent::foo" or select="key('wibble','wobble') it really makes no difference. The criterion for deciding whether a node is matched by a particular pattern only involves the node and its location in the current document, the expression used to select the node is simply not consulted during the matching process. select="child::foo selects the parent of the current node, match="child::foo" asks if that node is the child of anything. So unless you find it surprising that something can both have a parent and be a parent, I'm not sure what is surprising here?
