ACTION-762: Review 2.2.3 for language, do we mean tab, source, or
document order?

current: 2.2.3 Default Navigation Order (former 1.9.9): If the author
has not specified a navigation order, the default *sequential
navigation* order is the document order. (Level A)

Sequential navigation is defined in the glossary. We will need to
review 2.2.3 after the discussion of the glossary change proposed by
Jan [1].

There was confusion about the term 'document order'. the original
intent of the SC was to be sequential navigation of enabled elements
in source code order - the Lynx model of navigation - ignoring all
css. In other words in what order does the focus move when the user
hits the 'tab' key. Discussion ensued about using the rendered content
(rtl or ltr depending on language) to be the default order for
sequential navigation of enabled elements.
Most browsers (all that I have checked - ie, ff, chr, o) all move
through the document in source code order barring any tabindex
commands. Rather than making the browser change the default behavior,
we should not move to rendered content order.

recommend changing the wording to reflect specifically source code order
<new> 2.2.3 Default Navigation Order (former 1.9.9): If the author has
not specified a navigation order, the default *sequential navigation*
order is the document source code order. (Level A)
