Thanks for this new version.
I noticed one minor issue (carried over from previous versions) that
should be corrected. Section 5.1.1 says
If "avail" is false then the <fee:cd>
element MUST contain a <fee:reason> element (as described in
Section 3.9) and the server MAY eliminate some or all of the
<fee:command> element(s).
However, eliminating *all* of the <fee:command> elements isn't allowed
by the schema since the "command" element must appear at least once in
"objectCDType":
<complexType name="objectCDType">
<sequence>
<element name="objID" type="fee:objectIdentifierType" />
<element name="command" type="fee:commandType"
maxOccurs="unbounded" />
<element name="reason" type="fee:reasonType" minOccurs="0" />
</sequence>
<attribute name="avail" type="boolean" default="1" />
</complexType>
The "command" element should therefore be defined using minOccurs="0".
Otherwise, a server is forced to include an (empty) dummy command
element to satisfy the schema.
Note that the seemingly obvious change (use an XSD <choice> between
<command> and <reason>) won't work since there may be situations in
which commands are present (all unavailable with reason, such as "wrong
period") and the overall availability is false.
Best regards,
