or false.

|
Name
collisions are always avoidable with good planning.
|
|
|
2.
|
One
of the downsides of the use of XML vocabularies is their failure to provide simple element names to
describe data.
|
|
|
3.
|
Creating complex element names to avoid name collision would eliminate one of the
benefits of XML.
|
|
|
4.
|
Common XHTML element names like title, name, first, last, or address are likely to be
found in the thousands of XML vocabularies currently available.
|
|
|
5.
|
Once
a namespace has been declared, it can be applied to any descendant of the element.
|
|
|
6.
|
All
URIs are URLs.
|
|
|
7.
|
A URL
does not have to actually point to a real site on the Web to be used to define a
namespace.
|
|
|
8.
|
One
example of a URL is the identification of a book by its ISBN number.
|
|
|
9.
|
Currently URLs are rarely used in place of URNs but this may change in the
future.
|
|
|
10.
|
Using
URLs or URNs has not gained widespread acceptance in declaring namespaces.
|
|
|
11.
|
Nothing prevents you from using almost any unique identifier to declare a
namespace.
|
|
|
12.
|
It is
a good idea to verify that you have not added any syntax errors to a file after you have added
several namespace prefixes to the elements in a document.
|
|
|
13.
|
It is
required that you use namespace prefixes for all of the elements in a compound XML
document.
|
|
|
14.
|
Many
compound documents use a default namespace that covers most of the elements in the document, with
elements from other XML vocabularies assigned namespace prefixes.
|
|
|
15.
|
Unlike an element name, an attribute can be qualified by adding a namespace
prefix.
|
|
|
16.
|
Default namespaces apply to attributes but not to elements.
|
|
|
17.
|
The
class attribute is often used in CSS to apply common formats to groups of elements
|
|
|
18.
|
If a
namespace prefix is declared more than one, only the first instance is used in the style
sheet.
|
|
|
19.
|
Once
you have declared a namespace in a style sheet, you can associate selectors with that namespace by
adding the namespace prefix to each selector name.
|
|
|
20.
|
If
you omit the namespace prefix from a selector, the style sheet is rejected as invalid.
|
|
|
21.
|
When
the specifications for XML 1.0 were first posted, there was no support for namespaces.
|
|
|
22.
|
At
the outset of XML 1.0, there were several competing proposals for adding namespace support to XML and
CSS.
|
|
|
23.
|
All
browsers support the use of the @namespace rule.
|
|
|
24.
|
Vocabularies like RSS and MathML cannot be combined within single
documents.
|
|
|
25.
|
As
time goes on, browsers are less and less likely to extend and improve their ability to support
documents that combine multiple vocabularies.
|
|
|
26.
|
Currently, it is sometimes easiest to design XML documents that use multiple
vocabularies for viewing on specialized browsers.
|
|
|
27.
|
Browsers like Amaya and Jumbo include built-in support and style sheets for the
elements of the relevant vocabularies.
|
|
|
28.
|
The
elements of almost any XML document can be displayed in the current major browsers if you design
style sheets to work with the elements of the XML vocabulary.
|
|
|
29.
|
Every
element in a document that lacks a namespace prefix is considered part of the XHTML vocabulary if the
default namespace points to the URI for XHTML.
|
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.
|
A
document that combines several vocabularies is known as a(n) aggregate document.
_________________________
|
|
|
31.
|
A
name collapse occurs when the same element name is used from different XML vocabularies within
the same compound document. _________________________
|
|
|
32.
|
XML
offers hosts as a mechanism for distinguishing elements from one vocabulary from elements into
another vocabulary. _________________________
|
|
|
33.
|
A
glossary is a defined collection of element and attribute names.

|
|
|
34.
|
Applying a namespace to an XML document involves two steps.
_________________________
|
|
|
35.
|
To
declare a namespace you add the attribute xml:prefix= “uri” to an element within an
XML document. _________________________
|
|
|
36.
|
In
order to make a namespace available to all elements within a document, some XML authors add all
namespace declarations to the document’s root element.
_________________________
|
|
|
37.
|
If an
XML vocabulary is made widely available, the namespace associated with that vocabulary needs to be
unique. _________________________
|
|
|
38.
|
One
type of URL is a Uniform Resource Name. _________________________
|
|
|
39.
|
Currently, URNs are rarely used in place of URLs but this may change in the
future. _________________________
|
|
|
40.
|
The
main requirement of a URI is that it be standardized.
___________________________________
|
|
|
41.
|
To
apply an XML namespace, you give elements and attributes local names.
_________________________
|
|
|
42.
|
A(n)
unindexed name is a name without a namespace reference.
_________________________
|
|
|
43.
|
Like element names, there is no default namespace for attribute names.
_________________________
|
|
|
44.
|
As
with XML documents, the namespace prefix is required. _________________________
|
|
|
45.
|
Any
@namespace rules in a style sheet must come before all @import and @charset rules.
_________________________
|
|
|
46.
|
Any
@namespace rules in a style sheet must come after any style declarations.
_________________________
|
|
|
47.

If a
namespace prefix is declared more than once, only the first instance is used in the style
sheet. _________________________
