RE: [Openexr-devel] Long Names for Channels and Attributes

[Luc-Eric Rousseau]

Do you have a longer term plans to define group of 
channels, including groups of groups?  Presently
the grouping based on dot-separated names
with no spaces could limit the user interface.  

Also, can channel names be UTF-8? And if so, could 
a japanese string contain a byte value that 
could be mistaken for a dot?
