[2.0] store comments somewhere

[typemytype]

dont duplicate data as DS objects and custom syntax

in the lib?

would be hard, data change externally, storing line numbers is a bad idea

in the xml directly on write and read?

insert xml comments in the associated objects?

with etree.Comment("this is a comment") and insert this somewhere and read it back in?

storing comment isnt really that important at all

add notes tab

where users can store arbitrary info

maybe the easiest is not to support comments in the text editors and add a lib key for notes
