<moz-page-nav data-l10n-id="with-heading"
            data-l10n-attrs="heading"></moz-page-nav>

In which case your Fluent messages will look something like this:

with-heading =
  .heading = Heading text goes here

You also need to specify a data-l10n-id for each moz-page-nav-button:

<moz-page-nav-button data-l10n-id="with-button-text"></moz-page-nav-button>

with-button-text = button text goes here
