What is @xml:space about?
What is @xml:space about? Jesper Tverskov (at http://www.xmlplease.com/xml/xmlspace/) and Dimitre Novatchev (at http://stackoverflow.com/questions/11372222) say that @xml:space is, like <xsl:strip-space>, only about what to do with whitespace-only text nodes. Dimitre suggests that the spec might be ambiguous but that all implementations he knows read it as he does. But based on XML spec, fifth edition, 2.10 White Space Handling (http://www.w3.org/TR/xml/#sec-white-space), I think @xml:space is for telling an application whether it can proceed with whatever it was planning to do with white space inside a text node (such as collapsing it as an XSLT app making HTML might) or whether the application should preserve the white space found in the node. By this understanding, if an application collapsed white space in nodes, the white space-only text nodes too would get collapsed, but that would be an indirect (and inefficiently reached) result. Does @xml:space refer only to treatment of white space-only text nodes or to treatment of all text nodes? Thanks, John
