Hi,
 
We are currently evaluating XEP to see if it matches our needs and make a prove of concept.
One of the things which is a must for the project I'm working on is SVG support for filters and then blend:multiply.
This is a mutch used effect in the printing industry. To be more specific we need to be able to create PDF files which have a 2 layers over eachother with the multiply filter. Is there any chance this might be implemented any time soon?
 
Here is a piece of the fo to show what I mean.
 
<fo:block-container absolute-position="absolute" left="168.429mm" top="81.5mm">
 <fo:block>
  <fo:instream-foreign-object>
   <svg:svg width="108.641mm" height="108.642mm">
    <svg:defs>
     <svg:filter id="Multiply">
      <svg:feBlend mode="multiply" in="SourceGraphic" in2="BackgroundImage" />
     </svg:filter>
    </svg:defs>
    <svg:g>
     <svg:image x="0" y="0" width="108.641mm" height="108.641mm" xlink:href="images/RB ZWOLLE.jpg" /> 
     <svg:rect id="blauwvlak" width="68.88mm" height="108.641mm" fill="#00A2E5" style="filter:url(#Multiply);"/>
    </svg:g>
   </svg:svg>
  </fo:instream-foreign-object>
 </fo:block>
</fo:block-container>

 
The JPG is show with a partial rectangle over it whcich is blue and the JPG is visible through that layer with multiply (Also see Illustrator/Photoshop)
 
Thanks,
