[AstroPy] Empty char value for PARAM with vo.table

I'm working with some VOTable files that have tags like this:

<PARAM name="XYZ" datatype="char" arraysize="*" ucd="meta.id;meta.file" 

vo.table.parse reports:

vo.voexceptions.E14: file.xml:213:3: E14: value attribute is required 
for all PARAM elements

The spec is clear that the value attribute is required, but isn't clear 
about whether the value must be non-empty.  Is there a consensus on this?
