The {{Crossreference}} (a.k.a. {{crossref}} or {{xref}}) template formats text into a standardized style for an inline (not block-level) "(See also ...)"-type parenthetical to other Wikipedia material. When on different pages, these are unprintworthy Wikipedia self-references. When crossreferencing material on the same page, they are not. For block-level crossreferences, see the {{Hatnote}} meta-template and its various progeny ({{See also}}, etc.). The output is ultimately produced by Module:Hatnote inline. It actually does support a block-level mode, however, for special cases (see parameter documentation below).
