[X] Address the relationship/categorization of Handel's oratorios with relation to Wikipedia:WikiProject Opera. Are oratorios a subcategory of opera (i.e. "unstaged opera") or are they not-opera (like symphonies)? -- Oratorios are Oratorios and not Operas... may be cross-listed (like Semele and Acis) on the Category:Operas by George Frideric Handel and the handel operas template, but the page itself says "this is an oratorio" with perhaps a box about "operatic performances".
