It's not legal because of the way it breaks out: it fails to follow the rule that a location path step is an axis specifier followed by a node test (and optional predicates). > It works fine with my >version of Xalan... Both XT and Saxon gag on "///element". Thank goodness. Your version of Xalan does not conform in this respect. >And I think it's more logical to write /// than to write //, because for me >the first slash represents the root element and the second and third are the >short version for descendant-or-self, if you look at // you don't know (ok >YOU do know, but the average user doesn't) if it's starting at the root >element or if it has the meaning of .// It's not more logical to write "///" if you know that "//" is an abbreviation of "/descendent-or-self::node()/" (XPath 2.5). It is *not* "the short version for descendant-or-self": it's more precise than that. "//" doesn't start at the current node any more than "/element". It's not that hard. To suggest that it's "more logical" to do it a way that makes no sense according to the spec because the "average user" would be confused by what the spec says, and what the heck, is basically to say that it's okay to be confused, as long as we can make something up, and in fact we should encourage it, and what the spec says simply doesn't matter. Do any of us really want to go that way? Please don't defend Xalan's bug. My $0.02 (okay $0.03).
