recipe name: string citation title: string publisher: string year: restricted integer (e.g., 1900-2010) isbn: pattern with alternating digit groups and dashes introduction: string ingredients ingredient+ quantity: best to use a pattern since the example shows at least three variations, an integer, a fraction (1/4) or a range of numbers (3-5). measure: string (e.g., T, t, 28-oz can--you might try for an enumerated type but it is probably difficult to enumerate all the possibilities, such as 28-oz can) name: string processing?: string (e.g., drained, undrained, stemmed, etc)-might be omitted directions direction+: string comments? comment+: stringDiscussion: It is nice to have an overarching category for ingredients, directions, and comments that group all the elements of that group together. It makes each group seem like a block of related data, which is what they are. It also might make it a little easier for a program to retrieve those elements when using an XML parser. I felt as though comments might be optional, but you may well have concluded, based on the example, that comments are required. Many of you broke citation down into either a web reference or a published reference. That was an excellent distinction.
