Cannot generate from an XML schema with an xmlns that specifies an old version

[deinspanjer]

Expected behavior and actual behavior:

I was trying to generate some Java files based off an older XMLDatabase captured from jooq 3.5.4. The generator gave the following output:

[INFO] Using XML file           : /.../information_schema.xml
[WARNING] No schemata were loaded  : Please check your connection settings, and whether your database (and your database version!) is really supported by jOOQ. Also, check the case-sensitivity in your configured <inputSchema/> elements : null
[INFO] Excluding empty catalog  :
[INFO] Removing excess files

After trying a couple of different things, I eventually tried just replacing the xmlns line:
<information_schema xmlns="http://www.jooq.org/xsd/jooq-meta-3.5.4.xsd">
with one output by the current version:
<information_schema xmlns="http://www.jooq.org/xsd/jooq-meta-3.10.0.xsd">
and it worked with no further changes to the actual content of the file.

Steps to reproduce the problem:

• Generate an XMLDatabase
• Change the information_schema xmlns to an older version such as 3.5.4
• try to generate from the XMLDatabase

Versions:

• jOOQ: 3.10.0
• Java: 1.8.144
• Database (include vendor): MSSQL
• OS: Mac

Thanks for your report. Indeed, that should be done for this XML content type as well. jOOQ is already doing it for https://www.jooq.org/xsd/jooq-codegen-3.10.0.xsd, but apparently not for http://www.jooq.org/xsd/jooq-meta-3.10.0.xsd

This is in fact a duplicate of #6727.
I'll merge this to 3.10.6 (#7220) and 3.9.7 (#7221)
