I am developing an application for editing and validating formal metadata documents, which is XML-based. The metadata documents follow a structure which is represented by a DTD. The application is DTD-deriven. It should work with any valid DTD, so it does not depend on a specific DTD. 1. Two important issues about the validation are: - data type checking (ex: the content of <date> tags should have a valid date format) - validity domains (ex: for the content of <primary_colour> I should only accept "blue", "red" or "green"). As far as I undertand, XML-Data provides solution for the 1st issue, and I can work arround it in a DTD using a #FIXED attribute for those element declarations. However, I don´t see how XML-data or XML DTD provide information to meet the 2nd issue. 2. 2 questions about XML DTD's and XML-Data: - Can I use DTD to do everything that XML-Data does? - Using XML-Data, can I somehow get rid of XML DTD's?
