Subject: [geda-user] Difference between attached and detached attributes

Greetings,
I have been doing some symbol work in gschem and I got confused again 
about attached attributes vs detached attributes.  The manuals do not go 
into detail about usage.  Hint, hint.  Can someone tell me what is the 
difference between them and where I should apply one vs the other?

Right now, I am using attached attributes for everything except the pin 
attributes in my symbols. But the fact that there is that detached 
option there makes me wonder if I am using the correct type.  In other 
words, what is detached used for?  Then there is the "attribute 
promotion" issue.  Is there any impact on attribute promotion when using 
one or the other?
Any other "gotchas" when using one or the other?
Is there any problem with changing the attribute value after symbol 
instantiation from one or the other?

Thanks.
Girvin Herr
