It makes use of anoptionally securable (authentication and encryption) HTTP transport layer to convey XML-basedWCTP protocol exchanges between a WCTP client (the ACM AM) and the WCTP server (theACM AC).178517901795WCTP XML Element Common Data ItemsSome message exchanges are administrative in nature, similar to TCP open, accept, andacknowledgement messages which are not documented as a part of HL7, while others have adirect and obvious place in the ACM profile as transactions, such as PCD-06 and PCD-07.Please note, XML constant strings are presented in normal text. XML data to be filled in duringimplementation is presented in bold red text.The format of WCTP conformant timestamps (timestamp) is: yyyy-mm-ddThh:mm:ss.tttAll times are UTC. WCTP does not support the ability to indicate a time zone offset.Hours (hh) in 24-hour format, and .ttt is the optional number of millisecondsExample: 2011-01-19T20:33:52A push response URI is the URI (URL minus the HTTP://) used to identify the HTTP POSTdestination for WCTP replies and status updates.1800The notification text value is the actual text message to be presented to the wireless deviceoperator.The sender ID is the security identification of the IHE ACM actor to the WCTP receiver.1805The security code is essentially the password to go with the security sender ID.__________________________________________________________________________70Rev. 1.3– 2012-08-16Copyright © 2012: IHE International, Inc.
