Wow, that's great! Thankyou.

The writing style is great - it's very easy to read. There's a
surprising amount of detail in there but it doesn't feel that way.

I have a couple of specific comments ...

"Wherever this is the case, the Stan attribute name should be prefixed
or postfixed with an underscore."

It's probably best to forget about the prefixed version, it's something
we're trying to discourage anyway.

"Pretty-printing flattened Stan"

It's worth mentioning that introducing arbitrary whitespace into XHTML
content can affect how the browser renders the page so it should always
be double-checked for correctness.

"Built in renderers of the Page class"

The description of render_string should mention that it is really a
debugging aid (perhaps it should be renamed?) and should never to be
used to render real, human strings. render_string will break badly as
soon as it meets a unicode character that cannot be encoded to ascii.

render_sequence should mention that the "item" pattern is required.

Once again, thanks for writing this.

Cheers, Matt
