As far as I know, the combination of the SIM-XL mzIdentML output and the ms2 files SIM-XL uses work with our new visualisation tool, which is available at https://xiview.org
I thought this might be of interest to some in the SIM-XL community. I'm mentioning it here as there are not many other tools that correctly output cross-links in mzIdentML. If you do try using our xiView tool, please let us know if you encounter any problems,
