How do I share to an individual on LinkedIn, i.e., send a message to someone on LinkedIn?

The above link doesn't specify how to pass the LinkedIn id of the user.

The consensus appears to be: There is no way to setup a URL on LinkedIn to share to a particular individual.
If a user wants, they can select to send their message to everyone or to a particular person, but it is up to the user:
Look at the documentation URL you have: this question is so old, that the documentation now 404's and redirects to a blank page. Here's the new documentation: Official Microsoft LinkedIn Share Link API Documentation.
In fact, in 2013, you could use other parameters besides url, like summary and title. Since being acquired by Microsoft, LinkedIn Share API is now strictly limited to only the url parameter.
Seeing as they have been stripping other parameters from the API, I think it is unlikely that they will be adding new ones soon, even a to-user parameter.
