[XBL] Shadow parent or parents?

[Cyril Concolato]

Dear XBL experts,
This email comments on the 7 September 2006 LCWD of XBL 2.0.
In Section 5.7.1 "Selectors and Shadow Scopes", why use the term "shadow 
parents" ?
An element can only have one shadow parent ? it can only be distributed 
once ? Please clarify.
