Export XML differs from Export JSON ( SingleLogoutService_* is missing )

Example export:

<?xml version="1.0"?>

The XML version is not exporting the SingleLogoutService bindings. Bug or feature?

Start by tracing the repository's XML and JSON metadata export paths and comparing how the SingleLogoutService_Binding and SingleLogoutService_Location fields are handled. Reproduce the example export, then verify that XML includes the same SingleLogoutService bindings as JSON without changing the existing AssertionConsumerService output.
