GXL parsing Sukanya's result file

[Yuzo Kanomata <yuzok@ics.uci.edu>]

Hi All,

Sukanya wrote a converter java program to convert the bad syntax in the 
generated gxl file for Rigi I believe, to corrected gxl.

So far the data binding takes it in no problem. This was surprising in two 
ways:

1. What puzzled me at first was noticing it (Sukanya's gxl file) lacked the 
attribute xmlns:xlink in the gxl tag -- something the data bindings did not 
like in some other gxl files. What I now believe is happening is that for 
those files that use xlink in them, the parser in data bindings is 
complaining if it does not have a declaration of the XMl namespace for 
Xlink in it, which is want the <gxl xmlns:xlink "..."> stuff does.

2. The data binding did not complain that the required graph it attribute 
was missing:

is <graph>

should be something like <graph id ="some-id">

see dtd
<!ELEMENT graph (type? , attr* , ( node | edge | rel )* %graph-extension;) 
>
<!ATTLIST graph
   id          ID       #REQUIRED
   role        NMTOKEN  #IMPLIED
   edgeids     ( true | false ) "false"
   hypergraph  ( true | false ) "false"
   edgemode    ( directed | undirected |
                   defaultdirected | defaultundirected) "directed"
   %graph-attr-extension;
>

I'm not sure why the data binding lets this go ... I should perhaps try it 
with the validation methods turned on.
