[tei-council] dating-custom attributes https://sourceforge.net/p/tei/bugs/670/

[James Cummings]

I believe https://sourceforge.net/p/tei/bugs/670/ to be a 
corrigible error and will add 'custom' to the descriptions of the 
*-custom dating attributes to make them consistent if no one 
complains quickly.
