that makes sense to me. It seems the spec is once again confusingly 
worded. What you are saying is that the intention of the spec is to 
treat the text-decoration property actually as 4 separate inheritable 
properties like:

	Value: false | true | inherit
	Initial: false
	Inherited: yes

text-decoration-overline: ...
text-decoration-line-through: ...
text-decoration-blink: ...

Actually as color is inherited as well the properties are more like:

	Value: none | solid | inherit
	Initial: none
	Inherited: yes

	Value: auto
	Initial: auto
	Inherited: yes

With the prose then explaining that auto means the font color of the 
element the corresponding text-decoration-...-style property is 
explicit set on.

The current text-decoration property then just becomes a shorthand for 
the above.

If this interpretation of the spec intention is correct then FOP behaves
