I think I never understood the terms detached and attached until I
looked at the files itself :-)

Currently I think that symbol files have generally no attached
attributes themselves, there should be only text with strings like
xxx=yyy in symbol files, and these are converted into attached
attributes when symbol is included in schematic. And then they can be
modified, at least when they are promoted. Peted does currently promote
(nearly) all attributes, but does a smart filtering when saving
schematic files. Attributes are only saved as attached attributes in
schematic file when they differ from initial attribute in symbol file. I
think that works fine. What may not work is multiline attributes for
symbols. Top level multiline attributes in schematic files should be not
a big problem, but for multiline attribute in symbol files I have to do
some thinking about displaying and editing it.

One question is: Can Text elements have attributes themselves? I think
that is OK and maybe useful, but attributes having attributes should be
forbidden.
