Title: Updated specifications for subtitle handling

Updated HTMLBook specifications for subtitle handling to be in accordance with best practices stipulated in "Common idioms without dedicated elements" in HTML5 specification (http://www.w3.org/TR/html5/common-idioms.html#common-idioms)

If a section has a subtitle, it now must be encapsulated along with the main title in a `

` block, as follows:

````html

This is the title

This is the subtitle

````

Specification, Schema, and XSL tooling are all updated here in accordance with this change.
