Add header chunk

[Gallenkamp]

To have a nice SEO working html header, we need

<link rel="alternate" hreflang="en" href="[[~[[BabelTranslation? &contextKey=`web`]]? &scheme=`http`]]" \/\>

<link rel="alternate" hreflang=de-default" href="[[~[[BabelTranslation? &contextKey=`de`]]? &scheme=`http`]]" />

*backticks replaced for markup reasons.

MODX forums post on this

So we need a simple solution that places the current language and all available translations inside the header.

Header chunk including the current language

<link rel="alternate" hreflang="[[++cultureKey]]" href="[[~[[*id]]? &scheme=`full`]]" />
[[BabelLinks? &tpl=`hreflangTemplateChunk`]]

with hreflangTemplateChunk

<link rel="alternate" hreflang="[[+cultureKey]]" href="[[+url]]" />

Hreflang has no default value. We could use a system setting for that like

<link rel="alternate" hreflang="[[++hreflang]]" href="[[+url]]" />

So that you can put x-default into the context that should serve as default language. Babel does not provide the +hreflang placeholder, so only ++hreflang would work. Only, if the current page is in the default language.
