2. Protocol Specification

M2MXML may be encoded using a compact binary representation based upon the wireless binary XML format (wbXML). This format maintains the overall structure of the XML, but uses single byte binary tokens to represent tags, attributes and common attribute values.

2.1 Tag Tokens

This specification defines a set of simgle-byte tokens corresponding to all of the tags found in M2MXML. All of these tokens are defined within code page zero. The following table lists the tokens, all numbers are in hexadecimal.

2.2 Attribute Tokens

This specification defines a set of single-byte tokens represeting the attribute names and common values used in M2MXML. All of these tokens are defined in code page zero. The following two tables list the attribute names and values. All numbers are in hexadecimal.
