SVG tiny

Hello,

 

I have made the .ai icons (Adobe Illustrator CS3) and they also contain
transparency elements. 

 

Until now I had to provide icons in the SVG 1.1 format (<!DOCTYPE svg PUBLIC
"-//W3C//DTD SVG 1.1//EN") that allowed me to preserve the opacity of the
elements. Now I have to provide icons in the SVG 1.2 tiny format or SVG 1.1
tiny (<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1 Tiny//EN") but the
transparent artwork is rasterized.

 

Is there a plugin, script or other software that I should use?

Please let me know how can I handle this.

 

Thank you!

Lia
