padded parameter entities

Section 3.2.1 of the current spec says:

For interoperability, if a parameter-entity reference appears in a choice,
seq, or Mixed construct, its replacement text should not be empty, and nei-
ther the first nor last non-blank character of the replacement text should
be a connector (| or ,). 

Comment:

If parameter entities in this context are always padded with spaces, then
their replacement text will never be empty, right?
