Parent of fo:marker

Hi,

According to the XSF-FO spec (section 6.11.3) "It is an error if two or
more fo:markers that share the same parent have the same
"marker-class-name" property value."

Therefore the following fragment should be illegal becuase all of the
<marker> tags are children of the same <block>, and the
marker-class-name attributes are repeated. Nevertheless, at least two
XSL-FO formatting engines accept it without complaint (though they
process the <markers> differently!)


<flow flow-name="xsl-region-body"> 
<block font-family="Times" font-size="12pt">
<marker marker-class-name="hLeftPart"><inline>Header Left part
1</inline></marker>
<marker marker-class-name="fLeftPart">Footer Left part 1</marker> 
<block> Some simple dumb sample document</block>
<block break-before="page"></block>
<marker marker-class-name="hLeftPart">Header Left part 2 </marker>
<marker marker-class-name="fLeftPart">Footer Left part 2 </marker> 
<block>Hello world</block>
</block>
</flow>

My question is, would this fragment comply with the spec if each group
of <marker> tags were enclosed in a nested <block>, as shown below?


<flow flow-name="xsl-region-body"> 
<block font-family="Times" font-size="12pt">
<block>
<marker marker-class-name="hLeftPart"><inline>Header Left part
1</inline></marker>
<marker marker-class-name="fLeftPart">Footer Left part 1</marker>
</block> 
<block> Some simple dumb sample document</block>
<block break-before="page"></block>
<block>
<marker marker-class-name="hLeftPart">Header Left part 2 </marker>
<marker marker-class-name="fLeftPart">Footer Left part 2 </marker> 
</block>
<block>Hello world</block>
</block>
</flow>

(fo namespace implied throughout)

Thanks and regards,
Rodney
