Performance Criteria |
|
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
|
1. Represent structured data with XML |
1.1 Gather information by analysing data, documents and problem domains 1.2 Write well-formed XML document by incorporating proper structure and syntax 1.3 Validate XML document using validation tools 1.4 Format XML document using styling tools |
|
2. Access and manipulate XML document |
2.1 Create new XML document using an XML parser application programming interface (API) 2.2 Access and traverse elements and attributes using an XML parser API 2.3 Modify elements and attributes using an XML parser API 2.4 Delete elements and attributes using an XML parser API 2.5 Transform XML document into data object using an XML parser API 2.6 Transform data object into XML document using an XML parser API |
|
3. Create service-oriented application using XML |
3.1 Define web services architecture and platform elements 3.2 Develop and deploy web service applications using a language 3.3 Develop a client application to consume web service using a language |

|
Guidance information for assessment |
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
