I do not use FOP so I put your files through 
another processor and the box came out precisely at 100mmx200mm.

So it sounds like a FOP bug.

Note in your stylesheet you are following poor 
form in the declaration of result tree fragment 
variables with text nodes, rather than simply 
addressing the values of the elements with 
attribute value templates the way you did with your simple page master.

The following would produce the same result 
without the overhead of creating variables:

   <xsl:template match="area">

     <fo:block-container position = "absolute"
               top      = "{top}"
               left     = "{left}"
               height   = "{height}"
               width    = "{width}"
               background-color = "DarkSlateGray">

       <fo:block>
         <xsl:value-of select="content" />
       </fo:block>

And even if you needed variables later in the 
code, the following would be better:

   <xsl:variable name="width" select="width"/>

I hope this helps.
