// Before Hugo 0.49 we set the pseudo page kind RSS on the page when output to RSS.

// was RSS.
// For the page kinds that can have multiple output formats, the Kind should be one of the
// standard home, page etc.
// This test has this single purpose: Check that the Kind is that of the source page.
