I find the documentation is critically lacking with regards to the available options for a feature.

Here is an example of what I mean...

http://docs.telerik.com/kendo-ui/api/javascript/dataviz/diagram/layout#configuration-alignContent

The diagram Layout > alignContent feature "Specifies the alignment of the content."

Ok, but the documentation does not even say what the allowed values are. Instead, it just has "alignContent String (default: "start")".

Now, I guess the allowed values here are the same values allowed for an SVG text-anchor.
https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/text-anchor

How about adding those possible values to the api documentation, or including a link to the relevant area of the SVG specification?

Hope this makes sense.
