v0.3

• Support namespaces for elements and attributes
  • <foo xmlns="barURI"> will call startElement("foo",nil) followed by
    namespace("barURI") (and then attribute("xmlns","barURI",nil));
    you must apply the namespace to your element after creation.
  • Child elements without a namespace prefix that inherit a namespace will
    receive startElement("child","barURI")
  • <xy:foo> will call startElement("foo","uri-for-xy")
  • <foo xy:bar="yay"> will call attribute("bar","yay","uri-for-xy")
  • Runtime errors are generated for any namespace prefix that cannot be resolved
• Add (optional) DOM parser that validates hierarchy and supports namespaces
