Can spin-orbit use both all-E and ECP basis sets simultaneously?

[Meirong Lin]

Dear molpro users,

Can molpro porform spin-orbit coupling calculations using both all-electronic and
ECP basis sets simultaneously?

For example, to compute HBr mulecule by MRCI+SO, it seems that only all-electronic
basis sets can be selected for Br atom, because H atom has no ECP basis sets and
the commands
ci;hlsmat,ecp,......
cannot be used.

Is it right?
