Oxygen is in a different class of software than what I was talking  
about. I should have said that I was talking about software that hides  
the HTML language from the end user. That is, the end user takes some  
high-level actions and the piece of software generates HTML without  
the user having to know anything about HTML.

Oxygen is essentially a glorified text editor much like Eclipse JDT's  
Java editor. Oxygen lets you enter any text but also provides  
autocompletion and validation of the editor buffer. Oxygen most  
definitely isn't hiding the markup language from its user.

However, a program that is designed not to expose HTML to the user  
should always generate valid HTML. It doesn't make sense to put a user  
who knows nothing about HTML in charge of keeping the output valid.
