[oXygen-user] Copy the Document Type Definition of XML file

Hi! I'm trying to copy resp. to modify an XML document via XSL. Here I use the usual identity template: <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> Unfortunately the DTD definition of the source document is not copied at this way. Does anybody know how can I accomplish this? The only idea I had was that you can use <xsl:output> to write a DTD declaration with XSL. However, I have no idea how I can read out the declaration from the source XML document. Is this possible with XSL? Thanks for any suggestions! Rossen
