Creates a new node in the abstract syntax tree. This node can be o) a supported XSLT 1.0 element o) an unsupported XSLT element (post 1.0) o) a supported XSLT extension o) an unsupported XSLT extension o) a literal result element (not an XSLT element and not an extension) Unsupported elements do not directly generate an error. We have to wait until we have received all child elements of an unsupported element to see if any elements exist.
