Do we need err:XS0016?

Hi all,

For p:variable, p:with-option, and p:with-param, we have a static error
err:XS0016 that says:

"It is a static error if the select attribute is not specified."

But @select is required by the schema, so I wonder whether we need an
explicit error code here. I think that err:XS0008 covers this case.
