Thank you all for the information for the implementations. We have added the property to the Editor's Draft[1].

We didn't add <length> version though, as existing implementations don't support it, and we could add it in future if we've got enough interests from implementers.


Regards,
Koji

It's pretty universally defined to allow for vertical alignment.  That's pretty rarely a fixed number of spaces, specially when spaces have a 'soft' width (e.g. in justified-right text).  Even microsoft word sets them on a regular ruler...
