OMA DM Provisioning Files
4/8/2010
OMA DM commands are transmitted between the server and the client device in messages. A message can contain one or more commands. For a list of commands supported in Windows Mobile 6.5, see OMA DM Protocol Command Elements.
A DM message is an XML document. The structure and content of the document is defined in the OMA DM Representation Protocol (OMA-SyncML-DevInfo-DTD-V1_1_2-20030505-D.dtd) available from the OMA Web site.
Each message is composed of a header, specified by the SyncHdr element, and a message body, specified by the SyncBody element.
The following table shows the OMA DM versions that are supported in Windows Mobile:
| Version | Format |
|---|---|
OMA DM version 1.1.2 |
<SyncML xmlns='SYNCML:SYNCML1.1'> </SyncML> |
OMA DM version 1.2 |
<SyncML xmlns='SYNCML:SYNCML1.2'> </SyncML> |
