Dynamic UIM as its name implies, is UIM that is cached in the resource store - rather than static UIM (described in earlier sections) which resides on the file system - so that the server and client do not have to be rebuilt in order for a page to be displayed in an application. All string values in dynamic UIM documents must be externalized in properties files, which must also be cached in the resource store.
When creating a dynamic UIM document, only the PAGE element is a valid root element. All the UIM features (elements and attributes) referenced in UIM Reference for Pages and Views are supported for dynamic UIM, except for those which are listed in Unsupported Dynamic UIM features.
Refer to Maintaining Dynamic UIM Pages on details about how to maintain dynamic UIM pages in the Resource Store.
