Internals
সম্পাদনাThis template itself contains only interface logic: default values for parameters, and code to allow certain parameters to be extracted for use with allbooks categories. Internal code to implement the page layout is in template {{Subject page/core}}.
Parameter extraction is accomplished by transcluding the subject page from outside the Subject: and Template: namespaces. When this template detects that the transcluding page is not in either of those namespaces, it doesn't call the page layout sub-template {{Subject page/core}}; instead, it returns a string of the form /parent/parent2, where parent and parent2 are the parameter values specified to this template. Before attempting to extract parameters from the transcluded result, the caller verifies correct format of the result by passing it to template {{parsable}} — and if the format doesn't verify, the caller reports the problem to Category:Attention needed (allbooks).
