In his article in this issue, Peter-Paul Koch proposes adding custom attributes to form elements to allow triggers for specialized behaviors.
The W3C validator won’t validate a document with these attributes, as they aren’t part of the XHTML specification.
Now that you’ve defined the custom attributes, how do you place them where a validator can find them?The very best place to put them would be as the and adding the new attribute specifications at the end of the file.When adding attributes, you want to add your customizations at the end of the DTD to ensure that everything they need to reference has already been defined.IBM Web Sphere Application Server provides periodic fixes for the base and Network Deployment editions of release V7.0.The following is a complete listing of fixes for V7.0 with the most recent fix at the top.
Web Sphere Application Server V7 now offers web server load balancing and failover for up to 5 licensed application servers and a new merge tool for simplifying load balancing and failover configurations.This is provided by way of a free fix pack available to all base version Web Sphere Application Server V7 customers.The URL at the end of your DOCTYPE declaration points to a place where you will find the DTD for the flavor of HTML you’re using.Neither your browser nor the W3C Validator goes out to the web to find the DTD — they have a “wired-in” list of the valid DOCTYPEs and use the URL for identification purposes only.As you will see later, this will change when you make a custom DTD. For each attribute, you need to specify which element it goes with, what the attribute name is, what type of values it may have, and whether the attribute is optional or not.This information is specified in this model: Note: Adding new attributes to existing elements is easy; adding new elements is somewhat more difficult and beyond the scope of this article.
