XML I10-002 Exam - Topic 3 Question 36 Discussion

Question

Push the Exhibit Button to load the referenced "testml.xsd".

Assume that "testml.xsd" is defined. Without rewriting this XML Schema Document ("testml.xsd"), create a new, separate XML Schema Document to partially change the schema definition to write a cell Phone element as a child element of the person element. As a result, the following "XML Document" will be valid against the new schema. Which of the following correctly describes the new XML Schema Document? Assume the XML parser correctly processes the XML schema Location attribute.
