 There are places in the HTML Processor that need to parse differently
 according to whether text content is a sequence of NULL bytes or
 whitespace characters after decoding. It's awkward and inefficient to do
 this within the HTML Processor, however, as it requires eagerly decoding
 text nodes.

 The Tag Processor could expose a method to efficiently split apart a text
 node when needed, and then classify it, to aid in the parsing. This method
 could further be used to identify inter-element whitespace, which is
 usually ignored when rendering HTML.
