libxo allows the field description to carry two distinct format
descriptors, one for text/html and one for xml/json. The latter
defaults to the former:
xo_emit(" {:words/%7ju/%ju}", twordct);
For "w", this is does the right thing; in text mode, the command
string is truncated:

In XML mode, the command is not truncated.

(Yes, I'm likely the only plum user left in the wild.)
Thanks,
