Exam Objectives

Section 1 - Architecture (19%)

1. Determine the implications of a given architecture on XML design considerations
2. Select appropriate XML technologies for an architecture (XML Schema 1.0, XSLT 1.0, DOM2, SAX2, XPath 1.0, XQuery, Namespaces, DTDs)
3. Design functional components and interconnections for an XML application architecture
4. Assess performance trade-offs related to parsing, validation and transformation
5. Address XML security using XML encryption and XML signature
6. Implement Java classes through XML binding via Java Architecture for XML Binding (JAXB)

Section 2 - Information Modeling (22%)

1. Analyze data, documents, and problem domains
2. Represent structure in XML syntax (model data)
3. Use Namespaces appropriately
4. Define DTDs (declarations, reuse, external references)
5. Define schemas using XML Schema (declaration, structure [elements vs attributes, best practices], data types

data relationships, reuse, external references)
6. Determine when to use DTD versus XML Schema (legacy systems, scoping, run-time modification, constraints)

Section 3 - XML Processing (22%)

1. Analyze data integration points
2. Use the SAX2 API to manipulate XML data
3. Use the DOM2 API to manipulate XML data
4. Address validation/conformance and exception handling issues related to XML Schema (e.g. data typing and pattern matching)
5. Perform validation of XML documents
6. Access data using XQuery

Section 4 - Transformations (29%)

1. Define optimal rendering/transformation approach for each target (e.g. screens, print, pervasive)
2. Transform XML using XSLT (e.g. CDATA block, recursive name template calls, named vs matched templates, dynamic attributes)
3. Re-target XML for multiple formats
4. Use CSS to render XML or XHTML
5. Consider data rendering issues after designing data models
6. Traverse an XML document using XPath
7. Implement input screens using XForms
8. Demonstrate the use of include, import, id, idref, and keys

Section 5 - Testing & Tuning (8%)

1. Determine appropriateness of single versus multiple pass transformations, XSL extensions, XSLTC, XSL and $Schema inclusions
2. Optimize XML application execution (e.g. includes, import, id, idref, keys)
3. Create instances for testing XML applications (e.g. based on data model, boundary cases)
4. Refine design as necessary based on data model, data integration, data rendering, and data query issues
