CSS Techniques.

1.1 Using em or percent for properties that need to change

This technique supposedly relates to Guideline 1.3 Ensure that 
information, functionality, and structure are separable from 
presentation.

Which is fair enough. However there are no criteria relating to this 
technique. Can I assume that this is then a recommendation and that the 
setting of absolute widths on text say, is permissible to gain AAA 
compliance?

1.2 Using px for properties that do not need to be changed

The old guidelines said that you were only supposed to use relative 
units, however pixels are defined as relative units.

These 2 techniques open up a problem that was never fully resolved (at 
least not to me) in version 1. While the original version was too 
strict, these techniques seem too subjective.

Is it acceptable from an accessibility standpoint, to have a fixed 
width layout specified in pixels and text specified in em's?
