Hi Shane,

Using <script> in the way outlined in the examples (first and third
examples, section 3.3.1):

  <script type="application/x-javascript" ev:event="submit" ev:observer="form1">
    return docheck(event);

  <img src="button.gif" alt="OK">
    <script ev:event="DOMActivate" type="application/x-javascript">

will cause an error in current browsers, since the body of the script
tag will be executed on document load, regardless of the presence of
the @ev:* attributes.

I realise we could argue that XML Events 2 is not supposed to work in
current browsers, but I would also argue that:

 (a) it easily could, in just the same way that we're making XForms work in
      current browsers, by way of Ubiquity XForms;

 (b) support for standards in browsers is piecemeal, and uptake is patchy, so
     it's advisable to create standards that can not only be built
into browsers,
     but can also be implemented using script.

I believe that a simple resolution here is to leave <script> alone to
do what it currently does in HTML, and instead to introduce a
<handler> element. Since this element is not understood by current
browsers, the content will not be interpreted as script, and
therefore, will not be executed when the document loads.
