Re: Recursive declarations in XML Schema

Hi Armin,

Thanks for reporting this bug. There was some problem handling recursive
declaration involving "group". Now it's fixed in CVS.

Cheers,

I'm using Xerces 1.4.1 and when i use the xerces-sample DOMCount to
validate example.xml against the scheme MLterm.xsd I get this error
messages:

[Error] example.xml:8:15: Element type "Dollar" must be declared.
[Error] example.xml:9:17: Element type "_tuple" must be declared.

Can you tell me what is wrong with my recursive definition or is there a
bug in xerces?

Thanks,
Armin

Re: Recursive declarations in XML Schema

Posted by Armin Mueller <Da...@web.de>.

Thanks for the quick reply. I've downloaded the latest development snapshot 
and now most of recursive declarations are validated correctly. But I've 
still a problem with one XSD-File, also including a recursive declaration. I 
get following error messages:

[Error] example02.xml:14:19: Element type "_tuple" must be declared.
[Error] example02.xml:18:27: Element type "Struct2.EndeT" must be declared.
[Error] example02.xml:19:18: The content of element type "_tuple" must match 
"(string,int)".

I think there is still a problem.

Thanks,
Armin
