bug report.

[Jianwu Wang]

Hi guys:

   We met an exception on escaped character parsing of moml file. You 
can recur the exception by the following steps:
1, get one moml file (as model1.xml in attachement)
2, edit the moml file by adding "&lt;hello&gt;" in a certain <configure> 
(as model2.xml in attachement)
3, open the edited moml file (model2.xml)
There will be an exception when you "save as" the edited moml file 
(model2.xml) or "save" and "open" it. It is because "&lt;hello&gt;" is 
changed to "<hello>" when you save the file.

Any ideas? Thanks.
