should i be using:

<script type="text/ecmascript">

or

<script type="text/javascript">

from what I understand there is no difference between the two and ecmascript was designed to keep javascript standardized. Since it seems ecmascript is more of the standard way of saying javascript should I just run ecmascript. What effect will this have on browsers?

Implementations may also accept the script type "text/ecmascript" for backwards compatibility with SVG 1.1. However, this type is deprecated and should not be used by content authors.

There are different versions of ecmascript, some of which are not related to relevant JavaScript implementations. I think it is ecmascript 4 that ActionScript is based on, for example.

Many of the standardizations have never been implemented, especially by Microsoft (with its non-standard event model).
