I was wondering when someone was going to notice that. :-) I think 
robust processing requires not making too many assumptions about what 
you'll get from the XPath expression. Such assumptions include:

1. An XPath expression returns at least one node.
2. An XPath expression returns exactly one node.

I do not intend to have a function such as selectSingleNode in the API. 
All XPath expressions will return lists.
