  The problem could be reproduced with the same data and xmllint.
It's an entity expansion problem which could be reproduced easilly
with the same data using xmllint:

paphio:~/XML -> xmllint --dtdattr --valid --noent hallowelt.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE rnode SYSTEM "hallowelt.dtd">
<rnode>
    
   <f att1="J">
   hello world
   </f>
    
</rnode>
paphio:~/XML -> cat .memdump
      04:23:48 PM
 
      MEMORY ALLOCATED : 16, MAX was 49574
BLOCK  NUMBER   SIZE  TYPE
0         150      8 malloc()  in none(0) "nbktext"
1         149      8 malloc()  in none(0) "nbktext"
paphio:~/XML -> 

  it's really due to the entity content. It was easy to fix, the
patch as well as regression tests data have been commited to CVS

  thanks for the report,

Daniel
