Given that att.responsibility is becoming global (see [feature-requests:#443]), @source should also become global, since they belong together. See also [feature-requests:#465].

At Raleigh F2F: Assigning to myself to liaise with HC and see if we can agree at all. ;-)
There are three types of @source attribute currently:
http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-att.readFrom.html#tei_att.source
http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-att.source.html#tei_att.source
http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ref-normalization.html#tei_att.source
These are all related in some way (giving the source of something) but are significantly different from each other that making @source global should be treated with care. Presumably global @source would replace all 3 of these types of @source.
