29976 2016-11-03 11:20:38 +0000 [FO31] Schema for fn:analyze-string allows outermost element to have mixed content 2016-12-16 19:55:19 +0000 1 1 1 Unclassified XPath / XQuery / XSLT Functions and Operators 3.1 Candidate Recommendation PC All CLOSED FIXED P2 normal --- 1 mike mike andrew_coleman public-qt-comments oldest_to_newest 128030 0 mike 2016-11-03 11:20:38 +0000 The prose specification for fn:analyze-string says: The function returns an element node whose local name is analyze-string-result. This element and all its descendant elements have the namespace URI http://www.w3.org/2005/xpath-functions. The namespace prefix is ·implementation-dependent·. The children of this element are a sequence of fn:match and fn:non-match elements. This sequence is formed by breaking the $input string into a sequence of strings, returning any substring that matches $pattern as the content of a match element, and any intervening substring as the content of a non-match element. But the schema describes analyze-string-result-type with mixed="true", thus allowing an xsl:analyze-string element to have text node children. I believe this should be mixed="false". 128031 1 mike 2016-11-03 11:29:25 +0000 I guess one possible rationale for putting mixed="true" here is that it makes it legitimate to take the atomizing value of the fn:analyze-string element, for example one can do: substring-before(fn:analyze-string, (fn:analyze-string//fn:group[@nr='1'])) to get the text before the first captured group. (Atomizing an element with element-only content is not allowed, for paternalistic reasons.) I don't think that's a strong enough argument; though we might choose here to remain bug-compatible with 3.0. 128119 2 mike 2016-11-08 16:52:43 +0000 Decided to leave the schema saying mixed="true", but add a comment explaining the history. 128156 3 andrew_coleman 2016-11-11 14:02:01 +0000 Action A-660-04: Mike to add a note to F&O to explain that the outermost element of fn:analyze string allows mixed content. 128159 4 mike 2016-11-11 14:54:01 +0000 The required Note has been added.
