Greg,

While the use of 274-X basically eliminates the human error element of
entering aperture lists, not all packages output using the same "Standard".
 This is particularily noticable with "custom" shape apertures.  You would
be advised to send your fab shops some samples of your 274-X output and see
if they have any problems in advance of placing any new orders.

Regards

> Our CAD suppliers currently provide us with Gerber files in RS274-D
format, but several of our PWB suppliers have asked us to consider getting
files in RS274-X format to take advantage of the embedded aperture list.  
> 
> Has anyone seen any problems or difficulties with the newer RS274-X
format which we should be aware of?
