The <cscm:default> tag is part of the multichannel framework that lets you build portals for mobile devices.
This tag renders its contents only if the client's classification has been mapped to "default" or if the client is not recognized.
A classification of "default" can mean that the request was not resolvable to an existing classification label (defined in <project>\WEB-INF\client-classifications.xml) or that it resolves to an existing classification label called "default." Default is treated by the system as a typical PC-based browser.
