QUESTION: 10

Assume the use of XML Data like [XML Data] referenced in a separate window.
When a data element is present in XML Data, there are three possibilities for b element as shown in [XML Data b Element] (separate window). No other possibilities are available.
Consider inserting any XML data into an XMLDB using the methods shown in [Operation 1] or [Operation 2].

[Operation 2]
After validating against the following [DTD], insert XML data (having no validation errors) into the XMLDB (do not consider the existence of a document type declaration in the XML data).
When the b element value is "null", the value of the b element is null.
When the b element value is a character string other than "null", the b element value is 1 in [XML Data b Element].
When the b element is an empty element, the b element value is 2 in [XML Data b Element].
[DTD]
<!ELEMENT example (data+)>
<!ELEMENT data (a?, b?, c?)>
<!ELEMENT a (#PCDATA)>
<!ELEMENT b (#PCDATA)>
<!ELEMENT c (#PCDATA)>

Under the method described in [Operation 1], the three possibilities may not be clearly identified in some circumstances
Under the method described in [Operation 2], the three possibilities may not be clearly identified in some circumstances
The methods in [Operation 1] and [Operation 2] can clearly identify the three possibilities
The methods in [Operation 1] and [Operation 2] cannot clearly identify the three possibilities
