This value can be set true or false to switch a filter in and out of the display.

Example code:

   // Alternative ways of referring to a filter

   // and controlling its enabled state.  This assumes

   // the filter was instantiated with a <STYLE> tag previously.

   myFilters = myElement.filters;

   myFilter1 = myFilters.item(1);

   myFilter2 = myFilters.item("DXImageTransform.Microsoft.Alpha");

   myFilter1.enabled = true;

   myFilter2.enabled = false;
