or false.

1.
|
Schemas have entirely replaced DTDs for document validation.
|
|
|
2.
|
Schemas can be divided into internal and external subsets but a DTD is always placed
in a separate XML document.
|
|
|
3.
|
Support for a particular schema depends solely on the XML parser being used for
validation.
|
|
|
4.
|
XML
Schema supports a collection of built-in data types but does not allow users to define their
own.
|
|
|
5.
|
Attributes use the same collection of data types that simple type elements
do.
|
|
|
6.
|
All
elements require attributes.
|
|
|
7.
|
An
attribute may be required for one element and optional for another.
|
|
|
8.
|
Where
an element or attribute is declared determines how it can be used in the schema.
|
|
|
9.
|
The
choice compositor requires that child elements must appear either only once or not at
all.
|
|
|
10.
|
You
can combine the all compositor with the choice and sequence compositors.
|
|
|
11.
|
The
minOccurs and maxOccurs attributes can also be used with compositors to repeat entire sequences of
items.
|
|
|
12.
|
XML
Schema gives you less control over mixed content than DTDs do.
|
|
|
13.
|
The
code to specify the location of the schema file depends on whether the instance document has been
placed in a namespace.
|
|
|
14.
|
Specifying a schema in an XML document is treated only as a hint by validating
parsers.
|
|
|
15.
|
XML
Schema supports four general categories of data types.
|
|
|
16.
|
Derived data types share many of the same characteristics as the primitive data types
they are derived from, but with a restriction or a modification added to create a new data
type.
|
|
|
17.
|
XML
Schema allows for ample flexibility in the date and time format.
|
|
|
18.
|
The
xs:gYear data type is a date entered in the format yyyy-mm.
|
|
|
19.
|
An
integer data type can be constrained to fall within a range of values.
|
|
|
20.
|
When
data values belong to a range rather than a set of values, you can create a list of possible values
using the enumerate element.
|
|
|
21.
|
One
way to create a restriction based on the lexical space is by using a regular
expression.
|
|
|
22.
|
The
\# character type represents a digit from 0 to 9.
|
|
|
23.
|
A
named model group is a collection of elements.
|
|
|
24.
|
Unlike elements, attributes can be grouped into collections called named attribute
groups.
|
|
|
25.
|
If
you are interested in a compact schema that mirrors the structure of the instance document, you
should use a flat catalog design.
|
|
|
26.
|
To
associate a schema with a namespace, you first declare the namespace and then make that namespace the
target of the schema.
|
|
|
27.
|
If
you choose to use a vocabulary’s namespace as the default namespace for a schema, you do not
have to qualify any references to customized objects in the target namespace.
|
|
|
28.
|
One
use of the include element is to access a library of schema elements that can be combined in a
variety of different ways.
|
|
|
29.
|
Once
a schema is imported, any objects it contains with local scope can be referenced.
|
Modified True/False
Indicate
whether the sentence or statement is true or false. If false, change the identified word or
phrase to make the sentence or statement true.
|
|
|
30.
|
Like DTDs, schemas do not use a single form.
_________________________
|
|
|
31.
|
XML Schema was created to replicate all DTD functionality in a schema; it does
not support any data types beyond what can be found in DTDs. _________________________
|
|
|
32.
|
The
root element in any XML Schema document is the main element.
_________________________
|
|
|
33.
|
All
of the attributes in a document are, by default, complex types.
_________________________
|
|
|
34.
|
Declarations that are placed as children of the root schema element have global
scope. _________________________
|
|
|
|
|
|
35.
|
The
scale attribute in the figure above has local scope. _________________________
|
|
|
36.
|
The
minOccurs and maxOccurs values must be set locally within a complex type element.
_________________________
|
|
|
37.
|
When
the aggregate attribute is set to the value “true,” XML Schema assumes that the
element contains both text and child elements. _________________________
|
|
|
38.
|
XML
Schema divides its user-derived data types into two classes: primitive and derived.
_________________________
|
|
|
39.
|
Commands on the View menu whose icon appears pressed in indicate that those
elements are currently displayed in the Outlook window. _________________________
|
|
|
40.
|
The
xs:NMTOKEN data type is a text string in which blank spaces are replaced with a single blank
space, and opening and closing spaces are removed. ___________________________________
|
|
|
|
|
|
41.
|
The
figure above shows the xs:IDREF data type applied to the patID attribute.
_________________________
|
|
|
42.
|
Schemas do not allow numeric data types.
_________________________
|
|
|
43.
|
The
xs:float data type is a double precision floating point number.
_________________________
|
|
|
44.
|
Built-in data types fall into three categories: list, union, and restriction.
_________________________
|
|
|
45.
|
In a
union data type a restriction is placed on the facets of the base type.
_________________________
|
|
|
46.
|
Registrations can be used to define a lower and upper range for data.
_________________________
|
|
|
47.
|
Instead of a pattern involving specific characters, you usually want a more general
pattern involving entity types that represent different kinds of characters.
_________________________
|
|
|
48.
|
A
certificate can be appended to a character type or set to specify the number of occurrences
for a particular character or group of characters. _________________________
