you start off, in root template, selecting of complex types in xsd
<xsl:apply-templates select="//xs:complextype" /> you have template match complex types, don't have name, can output them name based on parent element.
<xsl:template match="xs:complextype[not(@name)]"> <xs:complextype name="{../@name}type"> <xsl:apply-templates/> </xs:complextype> </xsl:template> finally, have template match elements complex type, , add type attribute
<xsl:template match="xs:element[xs:complextype]"> <xs:element type="{@name}type"> <xsl:apply-templates select="@*" /> </xs:element> </xsl:template> here full xslt
