[relaxng-user] Converting Relax-NG to Schema and DTD

[Daniel Vogelheim]

Hi all,

Thanks for the feedback.

On the error messages from Trang: John Cowan posted a list of unique 
message further down this thread. I did the same, running a newer 
version of the schema through a newer version of Trang. I get ca. 160 
errors reported, with the unique error messages being:

error: "{0}" does not correspond to an ATTLIST declarations and so 
cannot be combined with "interleave"
error: other element declaration is here
error: sorry, ambiguous attribute choice not handled (attribute "{0}" 
from namespace "{1}")
error: sorry, cannot handle this kind of "choice"
error: sorry, cannot handle this kind of "group"
error: sorry, cannot handle this kind of "interleave"
error: sorry, cannot handle this kind of "optional"
error: sorry, combining definitions with combine="choice" is not supported
error: sorry, not handled: duplicate declaration of element "{0}" from 
namespace "{1}"
error: sorry, wildcards are not supported

Some of them I could work around, but others I have trouble seing the 
problem right away.
As some have recommended, the best way to proceed is probably to work 
through those errors and remove them through some scripted 
normalization, or manually by changing the source.


For comparison, these are the message from the XSD conversion: (4 total)
warning: choice between attributes and children cannot be represented; 
approximating
warning: cannot represent an optional group of attributes; approximating
warning: cannot represent required wildcard attribute; approximating

Note that these are all warnings about approximations, no errors. This 
is exactly what I want. :-)


Sincerely,
Daniel
