XML I10-002 Exam - Topic 6 Question 63 Discussion

Push the Exhibit Button to load the referenced "XML Document". Create an XML Schema Document for "XML Document". The definitions of this XML Schema Document require that the value of the level attribute of the record element must be singularly unique within the XML document, and further, that the level attribute of the scenario element must reference the value of the level attribute of the record element. Select which of the following correctly describes what should be written in " XML Schema " document (1).
A) <xs:element name='TestML' type='testmlType'> < xs:unique name= ' LEVEL ' > <xs:selector xpath= ' record ' /> <xs:field xpath= ' record/@level ' /> </ xs:unique > < xs:ref name= ' levelRef ' refer= ' LEVEL ' > <xs:selector xpath= ' scenario ' /> <xs:field xpath= ' scenario/@level ' /> </ xs:ref > </xs:element>
B) <xs:element name='TestML' type='testmlType'> < xs:unique name= ' LEVEL ' > <xs:selector xpath= ' record ' /> <xs:field xpath= ' @level ' /> </ xs:unique > < xs:ref name= ' levelRef ' refer= ' LEVEL ' > <xs:selector xpath= ' scenario ' /> <xs:field xpath= ' @level ' /> </ xs:ref > </xs:element>
C) <xs:element name='TestML' type='testmlType'> < xs:key name= ' LEVEL ' > <xs:selector xpath= ' record ' /> <xs:field xpath= ' record/@level ' /> </ xs:key > < xs:keyref name= ' levelRef ' refer= ' LEVEL ' > <xs:selector xpath= ' scenario ' /> <xs:field xpath= ' scenario/@level ' /> </ xs:keyref > </xs:element>
D) <xs:element name='TestML' type='testmlType'> < xs:key name= ' LEVEL ' > <xs:selector xpath= ' record ' /> <xs:field xpath= ' @level ' /> </ xs:key > < xs:keyref name= ' levelRef ' refer= ' LEVEL ' > <xs:selector xpath= ' scenario ' /> <xs:field xpath= ' @level ' /> </ xs:keyref > </xs:element>

I believe `xs:key` is necessary for uniqueness, but I can't recall if `xs:unique` would also work in this case.

I remember practicing a question similar to this where we had to reference attributes. I feel like `xs:keyref` is the right choice for the scenario element.

Okay, I think I've got a handle on this. The key is using the xs:unique and xs:keyref elements to enforce the uniqueness and referential integrity constraints. I'll walk through each option carefully to determine which one best matches the requirements.

Hmm, the unique level attribute for the record element and the referencing of that level in the scenario element is a bit confusing. I'll need to review the XSD syntax to make sure I understand how to properly define those constraints.

The unique constraint on the 'level' attribute of the 'record' element, and the keyref referencing the 'level' attribute of the 'scenario' element, seem straightforward. This looks like the correct approach.
