is there a clear and unambiguous description for the dx Attribute in  
the case where the XML character data within the 'tspan' element is  
null or space?  There is currently a difference in rendering between  
UAs, and no errata found.

The current description appears to be here:
http://www.w3.org/TR/SVG11/text.html#TSpanElement
but afaict this possibility is not described.

In my view whether the character data within the 'tspan' element is  
null or space it should be respected.

the rationale being that whereas in the attached example it is  
probable that there is a primary key column it is easy to conceive  
circumstances where a key would not be appropriate, or the key data  
may currently be unavailable, but one wishes to display the available  
data.

please cc my email address when replying.

regards

Jonathan Chetwynd
