This might happen if you have created the /content node via WebDAV,
for example - if you create it directly with a form that posts to
/content/* and /content does not exist yet, that should work.

Node "/sling/content" should be a "nt:unstructured" node. Is
"/sling/content" a nt:folder maybe?

This means that the nodetype of the node /content does not allow
arbitrary child nodes. Node types are a feature of JCR to put
constraints on child nodes and properties, eg. only allow "title",
"date" and "author" as properties and only subnodes of the node type
"book" [1]. But an important feature of JCR is that it allows to
define so-called residual properties and nodes (defining "*" in the
node type definition) that allows any nodes (also of any node type).
There is a built-in node type "nt:unstructured" that allows any
property and child node. The often used nt:file and nt:folder (and I
think /content is a nt:folder in Sling by default), are not so
flexible [2]. Since node types cannot be changed once the node was
created, you can add and remove any number of mixins to the node. For
node types and mixins and their definition in Jackrabbit see [3].
Sling contains a "sling:Folder" nodetype that works like nt:folder but
allows arbitrary child nodes and properties as well (like
nt:unstructured), and that one should be used for things like /content
(because nt:folder is useful when you mount the repository as WebDAV.
