Resources required for some Test Objectives

Hi,
Does anybody have inputs on the resources for the following objectives of the new 141?
2-F Determine when to use DTD versus XML Schema (legacy systems, scoping, run-time modification, constraints)
2-G Consider data integration and linking issues when designing data models (i.e., related to XLink/XPointer)
3-F Determine process implications when integrating XML data
3-G Address validation/conformance and exception handling issues related to XML Schema (e.g., data typing and pattern matching)
5-C Create instances for testing XML applications (e.g. based on data model, boundary cases)
5-D Refine design as necessary based on data model, data integration, data rendering, and data query issues

The new IBM Certification - Test 141 covers a wide array of topics from XML fundamentals, Schemas, Rendering to Transformations as well as the fairly new ones like SOAP and Web Services.
You can follow the various posts in this forum to get to know the various resources you would require in your efforts.
