Experiment on alternate SVG path syntax for better EXI compression

Hello SVG WG,

The attached is a input from Canon on a possible alternate SVG path
syntax which allows us to get better compression result when converted
into W3C Binary XML format (EXI).

ISSUE-2050 (path subelements): Consider additional path syntax 
<http://www.w3.org/Graphics/SVG/WG/track/issues/2050>

Any comments are wellcome.

Dear all,

As some of you may remember, we had some discussions during TPAC 2008 about how to use EXI for better SVG path compression.
During that discussion, I said that we made some experiments on applying EXI compression on path data structured as XML trees.
The results were showing that, although the current compact syntax does a really nice job, using EXI on XMLized path data would certainly improve the situation, at least in the scenarios we are aware of.
Please find some more details related to that topic in the attached pdf file.

Regards,
                youenn
