Well http://www.w3.org/TR/REC-xml/#AVNormalize says "For a character
reference, append the referenced character to the normalized value." so
that explains that the character references are not replaced by space
characters.

See http://www.w3.org/TR/REC-xml/#intern-replacement, it says "The
literal entity value as given in an internal entity declaration
(EntityValue) may contain character, parameter-entity, and
general-entity references. Such references MUST be contained entirely
within the literal entity value. The actual replacement text that is
included ... MUST contain the character referred to, in place of any
character references in the literal entity value".
