Adding rel value in validator

Hi,

 

I would like to add 2 rel value as I want them supported in the validator.

 

First is "generator". This specify that the website is generated or powered
by WordPress.

Second is "designer". This is referring to the WordPress theme is design by
a company.

 

I would be appreciate if you guys could let me know after you guys have
updated the validator with this 2 rel value.

 

Thanks!

 

Best regards,

Calvin Ho
