Standard DOM is well known as the worst and the most impractical to use
tree-based interface for XML. :-)

In which language you are using DOM? Many languages extended DOM to
support variable bindings. For example

Java:
http://docs.oracle.com/javase/1.5.0/docs/api/javax/xml/xpath/XPathVariableResolver.html

.NET:
http://msdn.microsoft.com/en-us/library/system.xml.xsl.xsltcontext.resolvevariable(v=vs.71).aspx

I don't have strong position here. If it's to hard to implement this for
implementors we can make it optional.
