I have been working through the Best Practices document to understand the  
relationships between the BPs and the WCAG 1.0 checkpoints. doing this, I  
began to wonder whether the references "This relates to WCAG n.n" are  
useful, or not perhaps misleading.

For example, COLOR_CONTRAST [1] and USE_OF_COLOR [2] are grouped together  
and there is a reference "This relates to WCAG 2.1 and 2.2". There are two  
BPs and two CPs, but the reference doesn't say which BP relates to which  
CP. More importantly, the BP is concerned with poor ambient lighting,  
colour coding of hyperlinks, and monochrome screens, while WCAG is more  
about "color deficits" (functional limitation of the user).

Another example, IMAGE_MAPS [3] has a reference to WCAG CPs 1.2 and 9.1,  
but doesn't actually have anything in common with them except that they  
are about image maps.

I feel that more explanation and qualification is needed, more than a  
simple cross-reference. When the Relationship between MWBP and WCAG 1.0  
document is complete, it would be more useful, in a possible future  
version of the MWBPs to link to it and remove the cross-references.
