Obsolete libvirt Go XML parsing API (no Go modules)

The obsolete Go package libvirt.org/libvirt-go-xml provided annotated Go struct definitions for parsing (and formatting) XML documents used with libvirt APIs.

This package is replaced by the new libvirt.org/go/libvirtxml package in order to switch to using semver and Go modules. Aside from the changed import path and versioning scheme, the new package API is fully compatible with this legacy package.

Software currently using this package will keep working, but no further development will take place. libvirt XML scheme elements/attributes introduced after 7.4.0 will never be available. Authors are strongly recommended to switch imports to point to the new package, to prepare for future Go toolchains which will mandate Go module support and semver.

For details of Go specific behaviour consult the Go package documentation.
