**IsPlainText** | Use Go's plain text templates parser for the templates. **Default:** _false_.
**IsHTML** | Used in situations only relevant for `HTML` type of formats, page aliases being one example.|
**NoUgly** | If `uglyURLs` is enabled globally, this can be used to turn it off for a given output format. **Default:** _false_.
+**NotAlternative** | Enable if it doesn't make sense to include this format in an the `.AlternativeOutputFormats` format listing on `Page`, `CSS` being one good example. Note that we use the term "alternative" and not "alternate" here, as it does not necessarily replace the other format, it is an alternative representation. **Default:** _false_.

+## Link to Output Formats
+
+ `Page` has both `.OutputFormats` (all formats including the current) and `.AlternativeOutputFormats`, the latter useful for creating a `link rel` list in your `head` section:
+
+ ```
+ {{ range .AlternativeOutputFormats -}}
+ <link rel="{{ .Rel }}" type="{{ .MediaType.Type }}" href="{{ .Permalink | safeURL }}">
+ {{ end -}}
+ ```
+
+Note that `.Permalink` on `RelPermalink` on `Page` will return the first output format defined for that page (usually `HTML` if nothing else is defined).
+
+This is how you link to a given output format:
+
+```
+{{ with .OutputFormats.Get "json" -}}
+<a href="{{ .Permalink }}">{{ .Name }}</a>
+{{- end }}
+```
+From content files, you can use the `ref` or `relref` shortcodes:
+
+```
+[Neat]({{</* ref "blog/neat.md" "amp" */>}})
+[Who]({{</* relref "about.md#who" "amp" */>}})
+```
