-// FIXME:
-// This can only parse basic XML: elements, attributes, processing
-// instructions, and comments are OK.
-//
-// It barfs on DOCTYPE declarations.
-//
-// There's also no checking being done for either well-formedness
-// or validity.
-//
-// NameTables aren't being used everywhere yet.
-//
-// Some thought needs to be given to performance. There's too many
-// strings being allocated.
-//
-// Some of the MoveTo methods haven't been implemented yet.
-//
-// LineNumber and LinePosition aren't being tracked.
-//
-// xml:space, xml:lang, and xml:base aren't being tracked.
