Command: GetCreateObjectAttrs
Namespace: urn:zimbraAdmin
Description: Returns attributes, with defaults and constraints if any, that can be set by the authed admin when an object is created.
GetCreateObjectAttrsRequest returns the equivalent of setAttrs portion of GetEffectiveRightsResponse.
GetCreateObjectAttrsRequest is needed becasue GetEffectiveRightsRequest requires a target, but when we are creating a object, the target object does not exist yet.

The result can help the admin console decide on what tabs/attributes to display for creating objects.
e.g. 1. Creating an account:

 <GetCreateObjectAttrsRequest>
   <target type="account"/>
   <domain by="name">test.com</domain>
   <cos by="name">standard</cos>
 </GetCreateObjectAttrsRequest>
 
 <GetCreateObjectAttrsResponse>
     <setAttrs>
           <a n="zimbraMailQuota"/>
               <constraint>
                   <min>1</min>
                   <max>3</max>
               </constraint>
               <default>
                   <v>2</v>
               </default>
           <a n="zimbraMailStatus"/>
           <a n="zimbraFeatureCalendarEnabled"/>
           ...
     </setAttrs>
 </GetCreateObjectAttrsResponse>
 

e.g. 2. Creating a server:

 <GetCreateObjectAttrsRequest>
   <target type="server"/>
 </GetCreateObjectAttrsRequest>
 
 <GetCreateObjectAttrsResponse>
     <target type="server"/>
     <setAttrs>
           <a n="zimbraLmtpExposeVersionOnBanner"/>
           <a n="zimbraXMPPServerDialbackKey"/>
           <a n="zimbraReverseProxyImapEnabledCapability"/>
               <constraint>
                   <values>
                       <v>IMAP4rev1</v>
                       <v>BINARY</v>
                   </values>
               </constraint>
           ...
     </setAttrs>
 </GetCreateObjectAttrsResponse>
