Subject: DOCBOOK: strange definition of & and < in iso-num.ent


In the XML entities file iso-num.ent (ISO Numeric and Special Graphic 
Entities V0.3 $Id: iso-num.ent,v 1.3 2002/06/13 17:39:20 nwalsh Exp $) 
there are the following two rather odd definitions of & and <:

<!ENTITY lt     "&#38;#60;"> <!-- LESS-THAN SIGN -->
<!ENTITY amp    "&#38;#38;"> <!-- AMPERSAND -->

which effectively define the &lt; entity as "&#60;" and &amp; as "&#38;".

In practice, this has little effect, since the XML spec predefines &amp; 
and &lt; as "&" and "<", and most tools won't modify those definitions, 
but it can cause some confusion.  You can see somebody relying on these 
definitions in http://www.mulberrytech.com/quickref/XMLquickref.pdf 
(where, on the second page, the list of Predefined General Entities 
gives these strange definitions of &amp; and &lt;).

Unless there is some subtle reason beyond my understanding why these 
definitions should be given as such, they should probably be corrected 
in the next release.
