Missing required entrytbl cols attribute?

Hello.

I'm nesting CALS tables with the entrytbl element and the schema doesn't re=
quire me to specify the cols attribute (I'm using RelaxNG + Schematron to v=
alidate). However, without it, the stylesheets complain. (I'm using DB 5.0[=
.1] here but I think it's the same in latest 5.2 RC.)

I did a quick look over the CALS spec here at https://www.oasis-open.org/sp=
ecs/a502.html and it does list it as required.

Is this then an omission in the DB schema? Or are the stylesheets in the wr=
ong here?

Thanks in advance for an answer or a pointer to relevant docs.
