DRUPAL and PLONE validator errors

Dear Sirs,

How two FOSS CMSs: DRUPAL and PLONE standards websites

http://www.digital-ecosystem.org/simpleblog_index
http://consen.info

are providing rather than 70 errors of validation?
http://validator.w3.org/

What have to be our strategy for building collaborative communities 
websites?

thanks in advance,
Ferran
