Overview

The value returned by each element call, wrapping the just-inserted node so attributes can be added with the Nokogiri terse-chain syntax:

xml.object.classy.thing!   # => <object class="classy" id="thing"/>

A plain method name appends to the class attribute, name! sets id (and content if given), name= sets that attribute, a trailing Hash adds each key as an attribute, and a block descends into the node. [] / []= read and write attributes directly. Semantics mirror Nokogiri::XML::Builder::NodeBuilder.
