I don't think having LineLength rule for xml is relevant. With XML indentation and a lot of nested tags (ie. system.xml), or with some tags that must have a full classname (ie. di.xml), it can be very counterproductive if not impossible.
That led us to exclude this rule from our checks, which is a shame since we don't see anymore legit alerts on .php files.
I suggest adding <exclude-pattern>*\.xml$</exclude-pattern>
to it.
