CSS namespaces in Internet Explorer

Using namespaces in CSS (MSDN): does someone know if this solution works in Internet Explorer? Something like this:

element\:local-name {
  color: green;
}

That is, by escaping the ':' token (a CSS delimiter for a pseudo-element) we actually select an element with a given local name? Is that possible? Does this solution require the MSXML library to get it work? I honestly don't know. If someone has tested something like this, please let me know.
