Hi, XPATH 1.0 defines the following three node-type tests: 1) comment() 2) processing-instruction(<opt arg>) 3) text() My assumption is that a YANG tree doesn't contain any nodes of type 'comment' or 'processing-instruction' and hence these filters would never match any nodes. However, it wasn't clear to me from reading 7950 or rfc6087bis-14 whether text() matches anything. In particular, does a YANG leaf node (except of type empty) always parent a text node that holds its value? Thanks, Rob
