Tuesday 11 January 2005 Arabica: Variables in XPath expressions

XPath expressions can include runtime evaluated variables - /one/two/three[@id = $sku] for instance. Normally you only see them in XSLT stylesheets, but they're there in the spec as little library extension point.

Committed a few changes to implement variables, together with the start of the scaffolding to allow apps to hand in their own variable resolvers.
