No, that is not correct. First,  CLDR is consumed by a number of other
packages, besides ICU, including most recently TwitterCLDR.  ICU is used in
the development of CLDR.
You could take the opportunity to inflence CLDR to benefit the JRE by
providing input into the CLDR process.

Also, I was not referring to using the ICU data generator ( in
org.unicode.cldr.icu ) but the parser and utility, ( org.unicode.cldr.util
 - particularly, CLDRFile ).

It's ironic and unfortunate timing, to independently pull in 21 at this
point. The data input in 21 was from the 2.0 release, ( 2011-May-25 ),
which by 2013 will be two years old.

It's not an unacceptable risk, but it may be an unnecessary one to work in
isolation. The parser does not match the spec in a number of areas. As I
noted, I myself have been a bit absent from these discussions, both
physically and in catching up on the i18n-dev mail digests. But I hope that
more conversation will be mutually beneficial.
