[om] Newbie questions on the meaning of the Attribution Element

No, an application is free to disregards the entire attribution
depending on its need. The OMObject needs to be a valid object
after stripping the attribution. In your example this means
that you would strip the attribution and reattach the new LaTeX
encoding after evaluation.

And yes if you would try to evaluate subparts of the OpenMath
object you would end up with an attribution you wouldn't want
to be attached to the result of the evaluation.

OK, so they are totally open to anything...does this mean that all 
applications need to understand all of the attributions of an element?  
Using your example of the LaTeX encoding, lets say that I have an 
application that is able to output the answer to 2+5, but it doesn't 
understand LaTeX.  The numbers and plus sign have been attributed so 
that you can output the string '2+5'.  My application operates on the 
2+5 to get 7.  I'm assuming that if it then outputs 7 in the XML
encoding using the content dictionary that provided the encodings for 
the other numbers, it will automatically output the correct attribution 
as well.  I'm asking this because there might be a way (no, I can't 
think of one off of the top of my head) to create an attribute that is 
'out of sync' with their corresponding elements.  If there isn't, then 
I can break my code into much smaller portions, having each portion 
operate only on the part of the OM object that it understands, rather 
than having to understand everything at once.
