No, it's "multicontent"'s job to handle it properly.

Or...

I discussed with Janne about this and he raised a good question (again):

  - What is text primitive?

In future everyone should use hypertext, xanalogical links and such. 
So is cursive, bolding, font size primitives also? What's defined to be 
text?

If original is just text and immutable can someone make lie tabloid from 
it, with text sizes etc.,  and say that it's original so what have I done 
wrong? Of course now we can check the origin and say that it doesn't 
really say that.

Well, an old scenario, I'll got at year 2004 an email from someone from 
this group and it contains just one enfilade:

"""
  blaa lbaa blaa...
  ..ibsum bara blump...

  ..did you saw last days Newsweek?
  [and a piece of content of that newsweek]

  .blaa blaa balaa..

      someone
"""

Is this right? Do we have only enfilade if newsweek content has got 
pictures? Can enfilade have multiple media types in content?

I don't know. Next clip tells only about content and I don't know how it 
is specified:

Is content RDFNode or enfilade or what?

This example didn't tell much about the sizes what's of course important.
I think we can discus about this better when Benja is here.

from libvob.lava.Demo.java:

So, this could be said something like:

nodeview.text = new LineBreakingHandler();

    - now we say that if content has text -> use line breaking.
    
g.add(new ContentVob(content));

    - size is still issue but I think I get it better after Benja draws 
      this new vob system better to my brains.
