I think the best would be to figure out first if xml2-config exists and if yes, use it, otherwise look for pkg-config. I expect xml2-config comes from developers of the project, while pkg-config is more a distro/packager variant, but the main argument would be that currently it works fine with xml2-config. If some distro has no longer xml2-config, then pkg-config will be used anyhow.
