Dave,

My vote would be for B, but I could live with A by setting line width to
.0000000001%

All,

This issue is similar to the stroke weight issue.

What should WebCGM say about the allowable values and treatment of the
character height style property of WebCGM set through the DOM?
   a)  Limit value of both NVCC and relative scale to >0?
   b)  Allow zero values for both NVDC and relative scale and adopt CGM
conventions?
Recommendation a)

Summary

Currently the WebCGM 2.0 DOM chapter has a restriction of the allowable
values for character height.  It limits the relative scale stroke width to
>0%, but doesn't address absolute NVDC as far as I can tell.   Both the CGM
standard (informative Annex D) and the WebCGM 2.0 Profile says the treatment
of a zero-valued Character Height Attribute Element is "minimum available".
