Hi Mike,

persistence schema does not actually define *version* attribute although
the documentation of the schema tells about its use:

/and indicate the version of the schema by
using the version element as shown below:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">/

It was recently raised in glassfish forum:

Thanks,
Sahoo
