libreoffice at lists.freedesktop.org is probably the best list for 
questions like these.  I'm forwarding to there.

The generic documentation at 
augmented with LibreOffice-specific 
is the authoritative documentation.

Those XML namespace URLs must not be changed.

Beside the generic OpenOffice-org-minimal-version dependency, there is 
also a specific LibreOffice-minimal-version dependency, see the above 
links to documentation.

File pathnames of configuration .xcs/.xcu files within the extension can 
generally be changed arbitrarily.  (In old times, when the configmgr 
loaded data only on demand, the pathnames of the .xcs/.xcu files had to 
match the hierarchical paths in the configuration, that is why you often 
see such configuration files still stored with such long pathnames.)

(The hierarchical paths mentioned in the configuration .xcs/.xcu files 
can generally not be changed, though.)

Hard to tell without seeing the contents of that file.  In general, UNO 
implementation names can be changed, as long as the corresponding 
implementation code is adapted accordingly.

FYI, LO has become very picky about duplicate implementation names. 
Therefore, if you change an extension identifier, you /must/ change all 
implementation names.  And, the other way around, if you change any 
implementation names, you should increment the extension version (in 
case you do not change the extension identifier anyway).

See the above links to documentation.  (Using the accept-by attribute to 
require users to agree to the license is just a PITA though, IMO.  But 
IANAL and YMMV, of course.)
