Comment:
> @gt7-void I believe the point here is that it's ok to fail some `xlint` checks to avoid adding diffs to the templates.

I thought it was preferred to fix all `xlint` checks any time a template is changed.

In any case: is there a clear preference for heredocs (indented vs. unindented)?

If unindented heredocs are preferred (or accepted), should `xlint` be able to ignore the heredoc block (or check that the heredoc is in the preferred format)?
