jQuery remote validation with server generated error message

I am using the Validation jQuery plugin to do some validation. I have a service which returns "true" and "false" right now and everything is great.

However, the error message I am using is "That name is already taken."

I want the error message to be "That name is already <a href="/item?id=543"> taken</a>." where that item id is something returned from the server. But I can't figure out how to return anything from the server other than a single true or false and still have the validation work.

I know I can do "The name xxx is taken" using JQuery.Format("The name {0} is taken") but I really want to give a hyperlink to the existing item, and I don't want to have to chan开发者_如何学运维ge the item pages to accept a name instead of an id.

The validation plugin handles this already, but the call type is "json", so you need to make sure the string (error message) is passed in quotes, like this:

"Error Message"

The plugin will use this as the displayed error message, handy eh? :)
