If I can read E262 correctly, ASV's implementation is the correct one (you 
might want to check this with Peter on svg-dev). Of course, E262 is a stupid 
standard and a little more dwimity would be nice but this is no reason for 
IE6 to break the standard.

Suggested workaround:

/* this is totally untested, but it would be great if it worked */
function isvgNonNumericSplit () {
    var preClean = new Regexp('^\D+');
    var postClean = new Regexp('\D+$');
    this.replace(preClean, '');
    this.replace(postClean, '');
    return this.split('\D+');
}
// add to the interface
String.prototype.isvgNonNumericSplit = isvgNonNumericSplit;

Of course, chances are that may not work. If so then we're left with the old:

function isvgNonNumericSplit (str) {
    var preClean = new Regexp('^\D+');
    var postClean = new Regexp('\D+$');
    str.replace(preClean, '');
    str.replace(postClean, '');
    return str.split('\D+');
}

Which looks very similar, except that the former can be called directly on 
the string as in mystring.isvgNonNumericSplit() where the latter can only be 
called as isvgNonNumericSplit(mystring). If possible I think we should use 
(everywhere) the former.

Has anyone figured out how inheritance works in E262 ? Or if it's only 
possible ?
