Using the "id" element correctly

Markup elements fall into two categories: instance-specific elements and Page-Set specific elements. (This is somewhat analogous to class versus instance members, for those familiar with object orientation).

If a given flake exists many times in a Page-Set, an instance-specific element is created multiple times. The id attribute of such elements needs to be pre-pended with _PAGEFLAKES_, such that each element has a unique id attribute.

Page-Set specific elements are created once, regardless of how many times a flake exists on a Page-Set. The id attribute of such elements must be unique, such that it does not conflict with other Page-Set specific elements. For example, <script> elements containing FUA code, or <link> elements referencing style-sheets are Page-Set specific.
