GoodRelations: xmlns vs. prefix

Hi Martin,

HTML5 seems to be deprecating xmlns in favor of prefix attributes:
  http://www.w3.org/TR/2012/WD-rdfa-in-html-20120911/#xmlns--prefixed-attributes

Can you please tell me whether GoodRelations plans to remove or deprecate xmlns in favor of prefix?  Do you have any guidance on how the community should use xmlns vs. prefix with GoodRelations during the transition?

Thanks!

Regards,
Dave
