Short description of error
Reading a Collada file exported by Blender, Collada DOM 2.2.1 reports the following warning:
Warning: The DOM was unable to create an attribute xmlns:xsi = http://www.w3.org/2001/XMLSchema-instance at line 11.
Probably a schema violation.
Exact steps for others to reproduce the error
It is related to this line in the output file:
If instead we use
<COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema" version="1.4.1">
there is no warning. The xmlns:xsi attribute was not included in Collada documents exported by previous versions of Blender. Looking at the Collada 1.4.1 spec http://www.khronos.org/files/collada_spec_1_4.pdf it seems xmlns:xsi is not a valid attribute.
