Same objection applies to html, fwiw.

There are, in fact, only five pre-defined internal entities in XML: lt,
gt, amp, apos and quot.  That isn't a lot to remember and from
experience it isn't a huge burden on the typist.  A DTD may define
additional ones (and you can define your own within the document).  

If you want to use any other characters that aren't part of the basic
character set then you'll have to use a character reference (&#NNN or
&#xHHH, where NNN is the decimal value of a Unicode character and HHH is
the hexadecimal).  Of course, you can define your own entities to
represent these characters, for your convenience.  Or you can import one
or more of the entity sets that have been compiled by W3C:
