Question 11

Entities can reference content found either in an external file or within the DTD itself.

Question 12

A(n) notation must supply a name for the data type and provide clues about how applications should handle the data.

Accepted Answer

Notations serve to provide a name and description that allows applications to handle the data properly.

Question 13

To test for validity, an XML parser must be able to compare the XML document with the rules established in the DTD.

Accepted Answer

To check the validity of an XML document, an XML parser must compare it to the rules specified in the DTD (Document Type Definition) or other schema. If the document conforms to the rules, it is considered valid. If it doesn't, the parser will report errors or warnings.

Question 14

A DTD can be used to enforce a specific data structure on document content.

Accepted Answer

A DTD (Document Type Definition) can be used to define the structure and elements of an XML (eXtensible Markup Language) document and enforce specific rules and constraints on the content. This allows for validation of documents to ensure they adhere to the defined data structure.

Question 15

One way to create a valid document is to design a document type definition, or DTD, for the document.

Accepted Answer

A DTD is a formal definition of the structure and syntax of an XML document, and it can be used to validate the document to ensure it conforms to the specified rules and constraints.

Question 16

It is best not to work with mixed content if you want a tightly structured document.

Accepted Answer

Mixed content refers to a combination of different types of content, such as text, images, and tables, within a single document. While it may be necessary to include mixed content in some cases, it can make the document more difficult to structure and format consistently, leading to potential errors and inconsistencies. For a tightly structured document, it is best to use consistent formatting and avoid mixed content whenever possible.
