marker value

(1) When I used a syntax
     <fo:retrieve-marker marker-class-name="stdfooter" />

FOP didn't report any error or warning. And the marker isn't getting
printed in the footer. Even if the document is of more than 1 page.

(2) Then I realised that
      <fo:retrieve-marker marker-class-name="stdfooter" />

should be
      <fo:retrieve-marker retrieve-class-name="stdfooter" />

Now if the document is of one page then it is not getting printed and
if it is of 2 pages then it is getting printed on second page only.

The simple page master is :-
<fo:simple-page-master
           master-name="rest-page"
           page-height  ="297mm"
           page-width   ="210mm"
           margin-left  ="2mm"
           margin-right ="2mm">
     <fo:region-body margin-top="118mm" margin-bottom="50mm" />
     <fo:region-before region-name="pageheader" extent="116mm"/>
     <fo:region-after region-name="pagefooter" extent="48mm"/>
</fo:simple-page-master>

<fo:page-sequence-master master-name="podoc">
     <fo:repeatable-page-master-reference master-reference="rest-page" />
</fo:page-sequence-master>

Then the page sequence is :-
<fo:page-sequence master-reference="podoc">
   <fo:static-content flow-name="pageheader">
       .........
       .........
       .........
   </fo:static-content>

   <fo:static-content flow-name="pagefooter">
       .........
       .........
      <fo:retrieve-marker retrieve-class-name="stdfooter" />
   </fo:static-content>
