Assumption in the SVG specifications

It seems that the SVG specifications assume that SVG is the only 
vector format in existence.  Quoting one of the specs on the site:

"In SVG Tiny 1.2, the 'image' must reference content that is a raster 
image format, such as PNG and JPG. SVG Tiny 1.2 does not allow an SVG 
document to be referenced by the 'image' element; instead, authors 
should use the 'animation' element for referencing SVG Documents."


"The 'animation' elements specifies an SVG document providing 
synchronized animated vector graphics. "

This leaves it impossible to embed non-SVG static vector formats, 
such as (for example), PDF, AI (Adobe Illustrator), CDR (CorelDRAW), 
CGM (Computer Graphics Metafile), SWF (Shockwave Flash), and DXF 
(AutoCAD and other CAD software). These are not 'raster image 
formats' and so the 'image' tag cannot be used ("must reference...a 
raster image format") and they are not SVG.

(The video element would permit embedding of time-based vector-based 
content, but static vector content has been orphaned, it seems.)

Could someone clarify if the intent of this specification was to 
exclude the use of all other possible static vector formats?
