ACTION-18 "Make research on implementations for BCP 47"

Hi all,

As input to my action on research about BCP 47, see the link below

http://www.langtag.net/

this page is not officially "approved" by the LTRU WG (which works on 
BCP 47), but many participants expressed their support for the page .

these implementations support well-formedness  of language tags:

http://unicode.org/cldr/data/tools/java/org/unicode/cldr/util/data/langtagRegex.txt
http://www.dpawson.co.uk/java/rfc4646.html
http://rubyforge.org/projects/langtag/

this implementations supports the well-formedness and validity check of 
language tags:

there is also a test suite:
