Here are the initial samples. They are done on Windows with IE and Netscape and PhotoShop and my imagination. Your imagination may vary. Please comment, raise issues, let me know if I'm on the right track, etc.
1.3.1 textbox
Note the automatically laid out caption to the left of the input
box, which is of a default size.

1.3.1 textbox with help
This style may be more appropriate for cases where the help is
specified as an attribute on textbox, if we are going to allow
that, since it won't contain markup. Note the mouse cursor over the
caption and the thin popup box in the style of image ALT tag popup
boxes.

1.3.2 password
Note that the supplied caption is too long to fit comfortably at
the left of the checkbox. Presumably this kind of caption placement
and font issue will be left to CSS and the default CSS styles. Note
the use of asterisks in the textbox for typing echo.

1.3.2 password
Note that the help text for the password example is specified as a
hyperlink to an HTML file. I've proposed a pop-up help window
displaying that HTML (which was left as an exercise to the reader).
I've given the window a slightly special appearance by removing
some of the usual window controls and putting a question mark as
the window icon.

1.3.4 selectOne radio style with one chosen element

1.3.4 selectOne radio style with no chosen element but first
element highlighted for choice
Is this reasonable?

1.3.4 selectOne checkbox style with one chosen element
Is this a reasonable thing to spec out; it is counterintuitive.

1.3.4 selectOne pulldown Default
Note that there is no chosen item just "-----"
People often do this canonically -- should we define it as a
behavior?

1.3.4 selectOne pulldown chosen

1.3.4 selectOne listbox default

1.3.4 selectOne listbox chosen

1.3.4 selectMany listbox default

1.3.4 selectMany listbox chosen

1.3.4 selectMany checkbox chosen
Another counterintuitive one. Keep?
