Bugs in the submitted foreign content tests

Dear Kris

There are some bugs in the foreign content tests Microsoft submitted:


<http://dvcs.w3.org/hg/html/raw-file/54697709a218/tests/submission/Microsoft/foreigncontent/foreign_content_002.html>
The baseline of the text is to be placed at 0 pixels from the top of the 
svg element, [1][2] so "FillerText" is hidden. A solution would be to 
change

   var svgNamespace = "http://www.w3.org/2000/svg";
   var textElem = document.createElementNS(svgNamespace, "text");

to

   var svgNamespace = "http://www.w3.org/2000/svg";
   var textElem = document.createElementNS(svgNamespace, "text");
   textElem.setAttribute("y", "1em");


<http://dvcs.w3.org/hg/html/raw-file/54697709a218/tests/submission/Microsoft/foreigncontent/foreign_content_012.html>
Given that the UA style sheet for SVG is to contain |svg:not(:root) { 
overflow: hidden }|, [3] the bottom half of the second square is cut 
off, because it has been positioned outside of the svg element. To avoid 
confusion when interpreting the pass condition ("…above a black 
square.") strictly, I suggest changing

   <svg width="200px" height="200px">
       <rect id="rect1" x="0" y="0" width="100px" height="100px" />
       <rect id="rect2" x="0" y="150"  width="100px" height="100px" />
   </svg>

to

   <svg width="200px" height="200px">
       <rect id="rect1" x="0" y="0" width="100px" height="100px" />
       <rect id="rect2" x="0" y="100" width="100px" height="100px" />
   </svg>

to ensure the entire square is visible.

HTML5 does not require that SVG elements implement the id IDL attribute. 
To limit the test to what it claims to test, change

   var idName = parentNode.childNodes[i].id;

to

   var idName = parentNode.childNodes[i].getAttribute("id");


A patch with the suggested changes is attached.
