How would you like the overflowing text to be placed in the general case?

Maybe it could be made even more clear, but any length value is already  
allowed in startOffset. SVG 1.1 First Edition didn't allow negative values  
in startOffset[1], but SVG 1.1 Second Edition allows that[2]. Nowhere does  
it say that values are restricted to the range 0-100%.
