Hi Ed,

I just compared to the doc:
"If the namespace of the tag is any namespace other than the empty
string or |http://www.w3.org/1999/xhtml|, throw a |FaceletException|
<cid:part1.05030601.01090001_at_mueller-bruehl.de>."

Of which tag? If somebody looks ahead to the table, she might guess
"jsf". To become clear, the tag "jsf" should be mentioned.

If I understood right, your intention is:

<html xmlns="http://www.w3.org/1999/xhtml"
       xmlns:jsf="http://java.sun.com/jsf" >
     <head jsf:id="head">[...]

equivalent to

<html xmlns="http://www.w3.org/1999/xhtml" >
     <head jsf:id="head">[...]

Error:
<html xmlns="http://www.w3.org/1999/xhtml"
       xmlns:jsf="http://myCompany.com/myNamespace" >
     <head jsf:id="head">[...]

And this one ignored by JSF (unknown tag):
<html xmlns="http://www.w3.org/1999/xhtml"
       xmlns:XXX="http://java.sun.com/jsf" >
     <head XXX:id="head">[...]

Right?

I still belive, this is not a good way.

Best Regards,
Michael Müller
