Hi FOP DevTeam,

I developed a way to generate multiple page-sequence on XSL without to change my XML, but the XML-XSL-PDF don't work, to make this work, first I need to generate the .fo file, then transform this to PDF.

if run:

fop.sh -xml sample.xml -xsl multiplePageSequence.xsl -pdf sample.pdf

I get follow output:

[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] FOP 0.20.5
[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] building formatting object tree
[INFO] setting up fonts
[ERROR] org.apache.fop.apps.FOPException: flow must be child of page-sequence, not fo:flow


but if I first generate the .fo file with:

xalan.sh -IN sample.xml -XSL multiplePageSequence.xsl -OUT sample.fo

then generate the .pdf file from .fo file with:

fop.sh -fo sample.fo -pdf sample.pdf

I get the follow output:

[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] FOP 0.20.5
[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] building formatting object tree
[INFO] setting up fonts
[INFO] [1]
[INFO] [2]
[INFO] [3]
[INFO] [4]
[INFO] Parsing of document complete, stopping renderer

The part of XSL that cause on the fly transformation to catch the ERROR is:

<xsl:template name="ctrlPage"> <xsl:if test="(position() mod 3) = 0">
<xsl:text disable-output-escaping="yes"><![CDATA[</fo:flow></fo:page-sequence><fo:page-sequence master-reference="A4" language="pt" country="br">]]></xsl:text>
<xsl:call-template name="header"/>
<xsl:text disable-output-escaping="yes"><![CDATA[<fo:flow flow-name="xsl-region-body">]]></xsl:text>
</xsl:if>
</xsl:template>


to close and open fo:flow and fo:page-sequence for

<xsl:template match="data">
       <fo:page-sequence master-reference="A4" language="pt" country="br">
           <xsl:call-template name="header"/>
           <fo:flow flow-name="xsl-region-body">
               <xsl:apply-templates />
           </fo:flow>
       </fo:page-sequence>
   </xsl:template>

I can't understand because on the fly don't woks and from .fo file generated from xml+xsl transformation work, maybe a bug of FOP, or I can't generate XML elements using CDATA from this form.

I post this in dev list because I think that this is a feature or a bug on FOP then I attached the XSL and XML files that the team can test this issue, and the code is better to read than my bad English ;)

Thanks for any help or tip
