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

Aren't they the same thing?  If there is 10 years per period, doesn't that
mean that there is an observation every 10 years?

Here's how our documentation describes it:

YPP(n, year, month)
Specifies data reported at intervals that are multiples of twelve months,
where n is a positive integer from 1 to 30, inclusive, indicating the
number of years per period. Year is a year number indicating a sample
ending year. Month is optional and is a month name indicating a sample
ending month. If month is omitted, DECEMBER is assumed.

So if I ask for quarterly GDP to be displayed at the frequency y(10,2000),
for example, I would get:

1960      427.14
1970      768.55
1980     1839.50
1990     4367.40
2000     7742.50

Isn't that what we are trying to do?

I know that this is very time series oriented so let me know if I'm missing
something important.

I wasn't sure if Y10 would indicate ten years of data since the definition
says "YPP n years per period" or data collected every 10th year. But if
it's the latter, that would be great.
