> Compliance with WCAG 2.0 helps go some way towards achieving

> these BPs. There are two possible levels of effort required, labelled 
> for simplicity with the keywords /nothing/, /something/ and /everything/. 
>
> Note that coverage may depend on WCAG compliance level achieved and so 
> a BP may appear in “something” and “nothing” lists (for example, 
> LINK_TARGET_ID). 
>
> To summarise, if your content already complies with WCAG 2.0, then in 
> order to achieve compliance with the MWBP, you need to do the following:
>
> *Nothing*: If a provision is labelled "*Nothing" *then content that 
> complies with WCAG 2.0 already complies with the provision so and no 
> further effort is necessary. The following list includes all of the 
> provisions that are marked '*Nothing*' is provided for completeness.( 
> Links in this section point to the relevant provisions.  Recommendation.
