Subject: ISO-8859-1 encoding and XmlDecl omision (was Re: [xsl] Looking up keys in a separate xml file) From: "John Meyer" <jmeyer@xxxxxxxxxxx> Date: Tue, 6 Jan 2004 10:36:03 -0500 |
David, I'm not sure I understand why <xsl:output method='xml' version='1.0' encoding='iso-8859-1' omit-xml-declaration="yes" indent="yes"/> is invalid. ISO-8859-1 is a subset of UTF-8 and should cause no problems since most parsers default to UTF-8 if the XML declaration is ommited. Secondly, the xml-declaration can be invalid when not outputting a well-formed XML document entity. This would occur when outputting only a document fragment. If the declaration must be output when a non-UTF encoding is used, this would cause serious problems outputting anything other than document entities. I believe the only constraint when using the XML output method is that the result must be a general parsed entity. I am interested in knowing if any xslt processors exhibit this behavior though. It would seem to be a debilitating limitation unless I am misunderstanding you. As I side note, I think all document entities should contain an XML declaration. The extra characters are nominal for memory requirements and can be significant aid in identifying the document characteristics.

The XSLt engine will be forced to ignore omit-xml-declaration="yes" here.
