[Flightgear-devel] loading aircraft-data/foo.xml or not...

[<wki...@gm...>]

is there some way to read a property (eg: aircraft-version) from the 
aircraft-data/foo.xml file before deciding to load it in its entirety, to load 
certain specific properties from it, or to ignore it completely?

the reason i ask is that sometimes when craft get updated, there may be 
properties (or missing properties) in the file that cause problems for a craft 
that has been updated... in all the cases i'm aware of, the fix was for the user 
to go behind the scenes and manually delete this file so the craft could start 
clean... but that's not always a GoodThing<tm> because there may be data in the 
file that is desirable (eg: hobbs clock) and doesn't cause problems...

my idea is for the craft to somehow be able to handle this situation itself 
without the user having to get involved behind the scenes or maybe think the 
craft is just broken and go complaining about it... or not...
