zero vector

I am looking for a way to notate the n-dimensional zero vector.  You 
can't use the vector tag with many zeros since the number of zeros is 
unknown. I am told this is normally displayed as a bold zero.  I am 
inclined to use <cn type='vector'>0</cn>, but this doesn't seem to be 
allowed according to the spec.  Any suggestions?
