my concern is of extentions. our underlying XML element is getting stored in the database as a "number". but the number (6) also has an human readable alias ("XYZ"). i wanted the schema to contain both types of information for display (string) as well as storage (number). i also want to constrain the data to an enumeration set (ie. today 1-5 are valid, next week its 1-8, ...) i'm a newbie to XML, so i am easily confused... ;-) thanks for the reply -----Original Message----- From: smohr Sent: Friday, May 05, 2000 9:54 AM To: xml-dev Cc: smohr Subject: Re: alternate enums in XML Schema I think you're confusing the role of the XML processor and the application built on top of it. You've typed the element as "number" but included string information. This relies on an implicit mapping to a string, which is properly the role of the application. If you are restricted to schemas, you have to look at the requirements. If the problem is one of extension, e.g., tomrrow I add 6 => XYZ, then type the element as an enumeration and bypass the numeric encoding. If the problem is one of changing the mapping, e.g., tomorrow 5 stops mapping to COM and maps to XYZ, schemas won't help you. Look at changing the authoring app or the consuming app or both with a data driven mapping -- possibly XML. ************************************************************************ *** This is xml-dev, the mailing list for XML developers.
