I can't see how that paragraph applies, I need further help with this!

My understanding is that that paragraph says that an implementation can choose
between delivering a sequence of items or an error, if both are the outcome of
evaluating an expression.

However in the case of:

declare function local:myFunc()
{
    e[928]
};
local:myFunc()

where does the empty sequence come from? Maybe one can infer it from the
fn:error() function, but hasn't yet been clarified how that one enters the
picture.

I agree, the none type surely gives us a lot of trouble :}
