XML I10-002 Exam - Topic 4 Question 16 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 replacing the phone element with a cellPhone 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 that the XML parser correctly processes the XML Schema schemaLocation attribute.
