Decker's reply certainly works. The following also works. In the head section of the master page:

  <script src='<%# Page.ClientScript.GetWebResourceUrl(typeof(ServerCtrlProjNameSpace.PickAnyClass), "ServerCtrlProjNameSpace.Scripts.dateValidation.js") %>' type="text/javascript"></script>

The inline data-binding expression is triggered by the following in the load event handler for the master page:

Page.Header.DataBind();
