[DDI-ADG] standards for frequency (or lack thereof)

And if these are used in SDMX, I imagine that they're machine actionable?

I'm wondering how this would work with my hope that someone could design a 
search interface where the user could select among several pre-defined 
frequency options; I was originally imagining a pull-down menu where the 
user would be able to choose among annual, monthly, etc.  But it sound like 
this would maybe be more compatible with a search box where they could 
format their search accordingly (e.g. put in Y10 for decennial).

I guess it's the difference between giving a set of discrete options vs. 
defining a system of frequency naming conventions that could hopefully be 
searched in a standard way.  The one San has presented certainly provides a 
lot more detail.
