[BUG] first line in .xml considered to be invalid

[BirgitBoss]

There are two files in the attached .zip file: both are assumed to be valid and should lead to successful certification.

issues_603.zip

Incorrect Result:

>>> result.dump()
←[91mInvalid xml: not well-formed (invalid token): line 1, column 1←[0m

First line is
<environment xmlns="https://admin-shell.io/aas/3/0">
The file *_fixed.xml was fixed with aasx package explorer
The original file *_corrected.xml - from my point of view - is also a valid xml file but leads to many many error (see #41)

Same result with line
<environment xmlns:aas=https://admin-shell.io/aas/3/0 xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xsi:schemaLocation=[https://admin-shell.io/aas/3/0 AAS.xsd](https://admin-shell.io/aas/3/0%20AAS.xsd)>
Or with

<?xml version='1.0' encoding='UTF-8'?>
<aas:environment xmlns:aas=https://admin-shell.io/aas/3/0 xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xsi:schemaLocation=[https://admin-shell.io/aas/3/0 AAS.xsd](https://admin-shell.io/aas/3/0%20AAS.xsd)>

I am sorry, I do not get the problem here. I am actually not able to reproduce it. Both

python -m aas_test_engines check_file ext/issues/43/issues_603/Aspect3.ttl.aas_corrected.xml --format xml
python -m aas_test_engines check_file ext/issues/43/issues_603/Aspect3.ttl.aas_corrected_fixed.xml --format xml

do not complain about invalid xml. However, they reject the file due many other problems. For example, Constraint_AASd-131 does not hold.
