Excellent, so we are on the same page here for how things should
look :))

yep. A little over zealous cut and paste from the original text:p ->
text:h from the generic proposal document.

An interesting observation, applications might track when a change takes
effect. For example, records like
ct1234 text:style-name Normal_1
ct1235 text:style-name foo
record that in given revisions then attributes are set to a given value.

and as the ODF+CT proposal says, the ac:change records the revision
where something is changed and the value *before* that change was
effective.
Thus the above immediate changes generate:
ct1235,modify,text:style-name,Normal_1
and the "foo" value is stored inline in the text:style-name attribute.

And the following four changes in immediate, ie, user sets style to foo
in ct12 while using the application:
ct12 text:style-name foo
ct13 text:style-name bar
ct14 text:style-name baz
ct15 text:style-name bob

gives on ODF+CT:

<text:p text:style-name="bob"
  ac:change001="ct12,insert,text:style-name"
  ac:change002="ct13,modify,text:style-name,foo"
  ac:change003="ct14,modify,text:style-name,bar"
  ac:change004="ct15,modify,text:style-name,baz"
...</text:p>

At ct12 you know style-name is inserted, and the value foo would be used
inline in text:style-name="foo". 

Just a little aside for those who are wishing to implement this in other
tools.
