Title: Additional fixes for #565.

- Escaped binding expressions.
- Cleaned up wording a bit.
- Tested code in jsbin and added some clarifications
based on things that were confusing to me. (In particular, the second
version of `` doesn't work with the previous
``, and configuring the element with camelCase
attributes is confusing because the actual property names end up lowercase.)
