Adding attributes to xs:appinfo?

[Arndt Jonasson]

XML Schema provides the element xs:appinfo for stating application
info. It can apparently contain any well-formed XML. Can it also
be supplied with application-dependent attributes? For example,
is the following fragment allowed (assuming app: is a declared
namespace
prefix)?

....
<xs:annotation>
<xs:appinfo appersistence="true"/>
</xs:annotation>
....

Checking the schema for schemas, this seems to be allowed according to
XSD second edition, but not the first edition!

Possibly a case of use with caution!
