[M4IF Technotes] SVG and MPEG-4

[robert.weetman kodak.com]

I am learning about SVG (scalable vector graphics) and came across the 
website of a company that is developing SVG related tools:
http://www.vectavision.com/Technology.html
The site claims: "MPEG 4: The SVG layer in MPEG4 allows all the benefits 
of SVG to exist within this motion picture format."
I know very little about MPEG-4 and I'm trying to understand what this 
means.  Browsing through specs and googling hasn't enlightened me much.
I have emailed the company but have not received a timely response.
Is there an "SVG Layer" in MPEG-4?
Perhaps the company simply phrased this poorly.  Any suggestions on what 
the company might really be trying to say?
Thanks for any help.
