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".
