Because it is very common to need to create, either temporarily or
permanently, invalid content. For instance, when I was writing
Processing XML with Java in DocBook I typed many xinclude:include
elements that were not provided for by the DocBook DTD. In other
cases I've added custom elements and attributes that are not supplied
by the DTD.
And in other cases, I do want valid markup. I just don't want it yet.
I'm not ready to fill in everything that's required. For instance, I
might begin a book by typing out an outline as section titles,
without actually giving the sections any content, though that is
ultimately required. But I can probably put together an outline in
day, even though filling in the content may take a year, as long as
the editor doesn't keep bugging me about the missing parts.
I've tried editors that attempt to maintain validity. And they're
just bloody annoying. Even if you want valid markup, they're either
pestering you with pop-ups; or filling in what they think you'll add
and guessing wrong. (There's often more than one possible child
element that can be added to make a parent element valid.) Bottom
line: they get in your way. They are not smart enough to figure out
what needs to be done, but they do something anyway.
