Not working with Raw HTML 1.4.10 and Premise 2.5

I am trying to use the following:

[show_to accesslevel='platinum']
 [raw]

 <div id="liquidTopMargin"></div> <!-- Provide a liquid upper margin for the SVG viewport. -->
  <svg id="svgElement" width="100%" height="98%"  ....

...
  </svg>
[/raw]
[/showto]

The svg displays properly, but [/showto] is displayed at the bottom of the page and the access control that should be provided by the Premise [showto] tag is ignored.

Any ideas?

Thanks
