No it's not. The SVG 1.1 spec says "For user agents that support CSS, the 
presentation attributes must be translated to corresponding CSS style rules 
according to rules described in section 6.4.4 of the CSS2 specification". 
Clearly the presentation attributes aren't independent of CSS, and I'm not so 
sure any more that it's right for Mozilla to implicitly add 'px' when doing the 
translation when given a unitless value. This will affect the CSS value returned 
by getPresentationAttribute, and it will inherit with the 'px'.
