If XHTML continues to mandate the use of a DOCTYPE, then in that case you have the option of defaulting the namespaces using DTD attribute defaults (er, except in IE, where the parser documents its non conformance here) > A workaround here is to use a different character: > > <try xin="try.xin"> > <svg.picture>pretty!</svg.picture> > </try> I'd just not use any prefix at all (which by the way would have a side benefit of matching mathml and perhaps svg in html5) You'd just use local names everywhere and conceptually (and perhaps in practice) an xin processor is just a processor that does an xslt transform something like <xsl:template match="*"> <xsl:param name="ns"/> <xsl:element name="{local-name()}" namespace="$ns"/> <xsl:copy-of select="@*"/> <xsl:apply-templates> <xsl:with-param name="ns" select=$ns"/> </xsl:element> </xsl:template> <xsl:template match="html"> <xsl:variable name="ns" select='http://www.w3.org/1999/xhtml'/> <xsl:element name="{local-name()}" namespace="$ns"/> <xsl:copy-of select="@*"/> <xsl:apply-templates> <xsl:with-param name="ns" select=$ns"/> </xsl:element> </xsl:template> <xsl:template match="math"> <xsl:variable name="ns" select='http://www.w3.org/1998/Math/MathML'/> <xsl:element name="{local-name()}" namespace="$ns"/> <xsl:copy-of select="@*"/> <xsl:apply-templates> <xsl:with-param name="ns" select=$ns"/> </xsl:element> </xsl:template> etc, so you just have certain predefined elements such as html or math that switch the namespace for all their descendants into the "correct" namespace until you get to the next "switching" element.
