No, no, no - sorry. XML is XML is XML. Please do not destroy a monument.
The XML Binary Characterization Working Group is tasked with gathering information about uses cases where the overhead of generating, parsing, transmitting, storing, or accessing XML-based data may be deemed too great for a particular application, characterizing the properties that XML provides as well as those that are required by the use cases, and establishing objective, shared measurements to help judge whether XML 1.x and alternate (binary) encodings provide the required properties.
