Alternate page-sequences

Hi All!

I have to create a report that has diferrent flows on odd and even pages. I am trying to create two page sequences and alternate them.
Here is a stylesheet (simplified):

	<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">

		<fo:layout-master-set>
			<fo:simple-page-master page-height="297mm" page-width="210mm"
					margin-top="5mm"
					margin-bottom="5mm"
					margin-left="15mm"
					margin-right="5mm"
					master-name="OddPageMaster">
		 	        <fo:region-body margin-top="1cm" margin-bottom="2cm"/>
			        <fo:region-before extent="1cm"/>
   				    <fo:region-after extent="2cm"/>
			</fo:simple-page-master>

			<fo:simple-page-master page-height="297mm" page-width="210mm"
					margin-top="5mm"
					margin-bottom="5mm"
					margin-left="15mm"
					margin-right="5mm"
					master-name="EvenPageMaster">
		 	        <fo:region-body margin-top="4cm" margin-bottom="2cm"/>
			        <fo:region-before extent="4cm"/>
   				    <fo:region-after extent="2cm"/>
			</fo:simple-page-master>

			<fo:page-sequence-master master-name="PageMaster">
				<fo:repeatable-page-master-alternatives>
					<fo:conditional-page-master-reference master-reference="OddPageMaster"
								page-position="any" odd-or-even="odd" />
					<fo:conditional-page-master-reference master-reference="EvenPageMaster"
								page-position="any" odd-or-even="even" />
				</fo:repeatable-page-master-alternatives>
			</fo:page-sequence-master>
		</fo:layout-master-set>
		

		<fo:page-sequence master-reference="OddPageMaster">
			<fo:flow flow-name="xsl-region-body">
				<xsl:for-each select=".......">
					<xsl:for-each select="......">
							<fo:block>odd</fo:block>
					</xsl:for-each>
				</xsl:for-each>
			</fo:flow>
		</fo:page-sequence>
		

		<fo:page-sequence master-reference="EvenPageMaster">
			<fo:flow flow-name="xsl-region-body">
				<xsl:for-each select=".......">
					<xsl:for-each select="......">
							<fo:block>even</fo:block>
					</xsl:for-each>
				</xsl:for-each>
			</fo:flow>
		</fo:page-sequence>
	</fo:root>

But it doesn't work.
 First, I get all pages for OddPageMaster (on both odd and even pages) and then I get the output for EvenPageMaster. What I want is to alternate them.

Any suggestion will be very appreciated.
Thanks,
Roxana
