Indeed, that is what it says:
http://www.w3.org/Submission/2006/SUBM-WebCGM20-20060313/WebCGM20-IC.html#webcgm_3_1_2_2

"CGM viewers shall ignore picture behavior specifications in URI fragments 
which are part of links from non-CGM content."

That text is linked from the .src description, "picture behavior rules".
