It can be seen as such a tool where the example instance is made
"persistent": instead of using it first time before "throwing it away"
and having to edit a schema to tweak and update it later on, the
instance has enough information to remain the source all over the life
cycle of the vocabulary.

That's exactly what examplotron is already!

For instance, in:

<?xml version="1.0" encoding="UTF-8"?>
<foo xmlns:eg="http://examplotron.org/0/";  
    eg:assert="sum(bar:percent)=100" >
    <percent eg:occurs="+">100</percent>

eg:occurs and and eg:assert are annotations to define the number of occurrences and an additional XPath rule.
