Person that edits VB form and person that wtites blog entry (one of the main
sources of web content these days) belong to different groups of actors
and these are completely different use cases.
There are more or less successfull applications on the market already
that support (or assist) WYSIWYG editing for the actor group
"Web Designer with at least basic knowledge of
html and its DOM". This kind of actors are ready to consume
concept of "properties of ancestor elements".
But there are no consistent WYSIWYG HTML/CSS editor applications
in the wild that support in full actor model "Writer without knowledge
of HTML and CSS". Simply because of the nature of HTML and CSS.
Think about <htmlarea> (WYSIWYG editor) or the like element
on the blog page. Or <htmlarea> that allow you to edit "richtext e-mail"
1) shall alow "richtext" editing without reading HTML specification.
2) shall alow to use of only structural constructs that have
strong and clear(consistent) semantic meaning.
3) reaction on all UI actions like pressing "Enter" key, Ctrl-B, etc.
shall be predictable upfront.
4) reaction on all UI actions shall be exactly reproducible - the same
set of actions in different instances of the widget shall produce exactly
same structure of the content.
5) shall not introduce new entites for the actor that are not related
to the main task: creating of the content.
6) shall present (render on the screen) only those markup element/attributes
that current actor can change in the current editing context (True WYSIWYG).
7) No hidden information is allowed - author and authenticity principle.

Here is what I do not understand in your use case:
Design of input forms implies design of server side code thus
set of programming skills and knowledge of some specific abstractions.
So actor here is a programmer - person
who knows about concept of two views: "source code" and
For the actor "Programmer", why do you think that
editing of text :
<input onvalidate="someformula"> is harder than
sequence of actions:
1) click on the toolbar
2) select 'onvalidate' property in editing property panel and
3) type that formula in the field that appear.

| CSS to show borders for div elements etc. as appropriate to support

Dave, I would like to hear your definition of the actor that
is supposed to use this. As for me your task really appears
a bit out of scope of HTML WYSIWYG editing.
