XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

I'd appreciate it very much if XOM had no hard dependency on Jaxen. The  
easy fix below requires no more than 5 minutes of work and makes no  
changes to the public API at all. Any particular reason that's not  
being done?

Node.java could simply read:

    public final Nodes query(String xpath) {
        return XPathHelper.query(this, xpath, null);
    }

    public final Nodes query(String xpath, XPathContext namespaces) {
                return XPathHelper.query(this, xpath, namespaces);
    }

With XPathHelper (or a similar class) being a XOM-internal class.
Thats's all there is to it.

Thanks,
Wolfgang.
