Attributes

QName Type Fixed Default Use Inheritable Annotation
conformance xs:string core optional 
The conformance level with which the Item is conformant.
dir restriction of xs:NMTOKEN optional 
The directionality of textual content (enumeration: ltr, rtl)
guid xs:string required 
The persistent, universally unique identifier common for all versions of the Item.

The major-minor version of the IPTC standard with which the Item is conformant.

xml:lang union of(xs:language, restriction of xs:string) optional 
Attempting to install the relevant ISO 2- and 3-letter
         codes as the enumerated possible values is probably never
         going to be a realistic possibility.  See
         RFC 3066 at http://www.ietf.org/rfc/rfc3066.txt and the IANA registry
         at http://www.iana.org/assignments/lang-tag-apps.htm for
         further information.

         The union allows for the 'un-declaration' of xml:lang with
         the empty string.
Wildcard: ANY attribute from ANY namespace OTHER than 'http://iptc.org/std/nar/2006-10-01/'
