Unexpected UnrecognizedAttributeError exception. (IPXACT: SPIRIT/1685-2009)

[Bernd Meyer]

I'm getting UnrecognizedAttributeError exceptions for documents which validated fine in my xml editor. The creation of the bindings completed without any errors/warnings and similar docs without attributes go through fine. I suspect that the problem might be related to the attributes of the spirit:baseAddress element which allows for a string of user defined attributes (prompt, xs:string). Please find below a small example:

Is there a switch to disable UnrecognizedAttributeError in cases like this?

Thanks, Bernd

There is no switch to disable UnrecognizedAttributeError specifically.

The fault appears to be that PyXB is not recursively collecting the
complete set of attributes supported for that element; specifically
the group spirit:configurable is not being included when
spirit:common.att is incorporated within spirit:long.att.

If you file a trac ticket at https://sourceforge.net/apps/trac/pyxb/
I'll look at this next time I'm working on PyXB.

I downloaded the git snapshot and reran the script on the entire Leon2 library. All 251 files passed.

Thanks, Bernd

Turned out to be premature expansion of an attribute group which had not itself been expanded. Tracked as https://sourceforge.net/apps/trac/pyxb/ticket/230, fixed in the next branch of the git repository.
