<p style="margin: 10px 0 0 0">Chad added the <tt>Pattern</tt> to the API after the fact. I'm not really sure how this was even supposed to be used, since according to Eclipse this class isn't used anywhere by other components. I guess makes sense, since only an SP would use I think...</p>
<p style="margin: 10px 0 0 0">It isn't 100% clear from the docs whether the <tt>Pattern</tt> is intended to be used always, or only when <tt>regexp=true</tt>. It sort of implies the former, in which case this really isn't an error b/c the scope value has to be a valid regular expression always (making the <tt>regexp</tt> attrib redundant?). Although the impl probably isn't correct since it should probably wrap the value in anchors when <tt>regexp=false</tt>. But that also doesn't seem right, because (for example) plain dots (such as in a domain name) in a regex are going to be evaled different than in a simple string match.</p>
<p style="margin: 10px 0 0 0">I think this wasn't very well thought out, actually. Probably <tt>Pattern</tt> should only be non-null when <tt>regexp=true</tt>. Otherwise the caller should just eval candidate values by string equality, etc.</p>
<p style="margin: 10px 0 0 0">Personally I wouldn't have done it this way, I don't like polluting the <tt>XMLObject</tt> interfaces with stuff like this b/c it can lead to failures in non-obvious places. But it's in the API, so we can't remove at the moment.</p>
<p style="margin: 10px 0 0 0">Need to decide something, b/c v3 has the same bug, the code was copied over as-is (although interface and class names are changed to <tt>Scope</tt> and <tt>ScopeImpl</tt>). </p>
