other subtyped (for lack of a better word) elements in the schema -- e.g., the input and button elements -- use a naming convention that ends with the string ".elem". But the current meta element patterns put .elem. in the middle of the pattern name; e.g., "meta.elem.name". Processing the schema would be easier if the meta patterns were consistent with the other patterns; e.g., "meta.name.elem" instead. The attach patch implements that re-naming.
