tests: test suite break when path contains #

[hseg]

Building from https://aur.archlinux.org/packages/python-cyclonedx-lib, I am getting ~400 errors if the path to the project contains a # character.
Log attached
error.log

Could you provide a reproducible setup/example?

It appears, that XMLSchema()'s file argument must not include a #, as it would be stripped, since the path is treated as a url.

I need to check with the leveraged https://pypi.org/project/lxml/ project, maybe there is a fix, or workaround, or an existing report/solution/advice.

I don't have much free time at the moment, if no one has fixed this by 2024-03-17 I'll take it on.

Tried tackling this, one complication to look out for is that `lxml` makes heavy use of cython, which I'm having trouble debugging. I'm giving up on this one. One thing I _have_ noted playing around with this is that what is significant is the real path to the test files - in particular, a usable workaround is to have a clone somewhere with a saner path, and to have a symlink to it in the desired location.
