To access output formats, each `Page` object provides two methods: [`OutputFormats`] (for all formats, including the current one) and [`AlternativeOutputFormats`]. Use `AlternativeOutputFormats` to create a link `rel` list within your site's `head` element, as shown below:
```go-html-template
{{ range .AlternativeOutputFormats -}}
{{ range .AlternativeOutputFormats }}
<link rel="{{ .Rel }}" type="{{ .MediaType.Type }}" href="{{ .Permalink | safeURL }}">

You can create a shortcode that will accept both named and positional arguments, but not at the same time. Use the [`IsNamedParams`] method to determine whether the shortcode call used named or positional arguments:
```go-html-template {file="layouts/shortcodes/image.html"}
{{- $path := cond (.IsNamedParams) (.Get "path") (.Get 0) }}
{{- $width := cond (.IsNamedParams) (.Get "width") (.Get 1) }}

{{ $width := cond (.IsNamedParams) (.Get "width") (.Get 1) }}
{{ $alt := cond (.IsNamedParams) (.Get "alt") (.Get 2) }}
```
This example uses the `cond` alias for the [`compare.Conditional`] function to get the argument by name if `IsNamedParams` returns `true`, otherwise get the argument by position.
