Test 142: XML 1.1 and Related Technologies
这是IBM XML 认证考试的Objectives，距考试的时间也不多了，加油！
The test consists of five sections containing a total of approximately 49 multiple-choice questions. The percentages after each section title reflect the approximate distribution of the total question set across the sections.
Section 1 - Architecture (19%)
- Determine the implications of a given architecture on XML design considerations
- Select appropriate XML technologies for an architecture (XML Schema 1.0, XSLT 1.0, DOM2, SAX2, XPath 1.0, XQuery, Namespaces, DTDs)
- Design functional components and interconnections for an XML application architecture
- Assess performance trade-offs related to parsing, validation and transformation
- Address XML security using XML encryption and XML signature
- Implement Java classes through XML binding via Java Architecture for XML Binding (JAXB)
Section 2 - Information Modeling (22%)
- Analyze data, documents, and problem domains
- Represent structure in XML syntax (model data)
- Use Namespaces appropriately
- Define DTDs (declarations, reuse, external references)
- Define schemas using XML Schema (declaration, structure [elements vs attributes, best practices], data types
data relationships, reuse, external references) - Determine when to use DTD versus XML Schema (legacy systems, scoping, run-time modification, constraints)
Section 3 - XML Processing (22%)
- Analyze data integration points
- Use the SAX2 API to manipulate XML data
- Use the DOM2 API to manipulate XML data
- Address validation/conformance and exception handling issues related to XML Schema (e.g. data typing and pattern matching)
- Perform validation of XML documents
- Access data using XQuery
Section 4 - Transformations (29%)
- Define optimal rendering/transformation approach for each target (e.g. screens, print, pervasive)
- Transform XML using XSLT (e.g. CDATA block, recursive name template calls, named vs matched templates, dynamic attributes)
- Re-target XML for multiple formats
- Use CSS to render XML or XHTML
- Consider data rendering issues after designing data models
- Traverse an XML document using XPath
- Implement input screens using XForms
- Demonstrate the use of include, import, id, idref, and keys
Section 5 - Testing & Tuning (8%)
- Determine appropriateness of single versus multiple pass transformations, XSL extensions, XSLTC, XSL and Schema inclusions
- Optimize XML application execution (e.g. includes, import, id, idref, keys)
- Create instances for testing XML applications (e.g. based on data model, boundary cases)
- Refine design as necessary based on data model, data integration, data rendering, and data query issues
