[SoapRMI] Re: [SoapRMI] About-XmlPullParserFactory

[Aleksander Slominski]

hi,

as far as i can see it is *bug* in JSX that it is not supporting fully 
XML 1.0 ...

did you use the latest version of JSX (they have both JSX1 and JSX2) as 
it seems thaye may be using "home grown" XML parser (see this entry 
(...) /XML1.0 spec/: either " or ' now can be used to delimit attribute 
values. Also, > characters are now permitted within attribute values. 
Both changes are to hew closer to the XML 1.0 specification. The empty 
tag was also implemented.(...) in 
http://www.csse.monash.edu.au/~bren/JSX/done.html) that may indicate 
that its comaptibility with XML limited (but improving) so they may 
appreciate  if you report the problem to their mailing list as an 
incorrect assumption about what needs to be escaped in XML attribute 
value: http://groups.yahoo.com/group/JSX-ideas/messages

hope it helps.
