handling alternative namespace in ifcxml

[GoogleCodeExporter]

Some CAD programs (like ArchieCad) that export to ifcxml, don't use the 
namespace 
xmlns:ex="urn:iso.org:standard:10303:part(28):version(2):xmlschema:common"

Instead there is:

- xmlns:ex="urn:iso10303-28:ex"
or
- xmlns:doc="urn:oid:1.0.10303.28.2.1.3".


When deserializing those files you get error:
System.InvalidOperationException : There is an error in XML document (2, 2).
  ----> System.InvalidOperationException : <iso_10303_28 xmlns='urn:iso10303-28:ex'> was not expected.


If I change namespace in the file manually deserialization works fine.

Probably Ifc-DotNet lib should handle those files also.

Thanks for the issue report.  It would seem the other programs generate 
non-standard IfcXml.  At some point in the future Ifc-dotnet will have to 
support those, but it's a low priority at the moment.
