- character
-
An atom of information, for example a letter or a
digit. Graphic characters have associated glyphs, where as control
characters have associated processing semantics.
- character encoding scheme
-
A function whose domain is the set of
sequences of octets, and whose range is the set of sequences of
characters from a character repertoire; that is, a sequence of octets
and a character encoding scheme determines a sequence of characters.
- character repertoire
-
A finite set of characters; e.g. the range
of a coded character set.
- code position
-
An integer. A coded character set and a code
position from its domain determine a character.
- coded character set
-
A function whose domain is a subset of the
integers and whose range is a character repertoire. That is, for some
set of integers (usually of the form {0, 1, 2, ..., N} ), a coded
character set and an integer in that set determine a
character. Conversely, a character and a coded character set determine
the character's code position (or, in rare cases, a few code
positions).
- conforming HTML user agent
-
A user agent that conforms to this
specification in its processing of the Internet Media Type
`text/html; version=2.0'.
- data character
-
Characters other than markup, which make up the
content of elements.
- document character set
-
a coded character set whose range
includes all characters used in a document. Every SGML document has
exactly one document character set. Numeric character references are
resolved via the document character set.
- DTD
-
document type definition. Rules that apply SGML to the
markup of documents of a particular type, including a set of element
and entity declarations. [SGML]
- element
-
A component of the hierarchical structure defined by a document type definition; it is identified in a document instance by descriptive markup, sually a start-tag and end-tag. [SGML]
- end-tag
-
Descriptive markup that identifies the end of an
element. [SGML]
- entity
-
data with an associated notation or interpretation; for
example, a sequence of octets associated with an Internet Media
Type.[SGML]
- HTML document
-
An SGML document conforming to this document type
definition.
- markup
-
Syntactically delimited characters added to the data of a
document to represent its structure. There are four different kinds of
markup: descriptive markup (tags), references, markup declarations,
and processing instructions.[SGML]
- may
-
A document or user interface is conforming whether this
statement applies or not.
- message entity
-
a head and body. The head is a collection of
name/value fields, and the body is a sequence of octets. The head
defines the content type and content transfer encoding of the body. [MIME]
- must
-
Documents or user agents in conflict with this statement
are not conforming.
- SGML document
-
A sequence of characters organized physically as a
set of entities and logically into a hierarchy of elements. An SGML
document consists of data characters and markup; the markup describes
the structure of the information and an instance of that
structure.[SGML]
- shall
-
If a document or user agent conflicts with this statement,
it does not conform to this specification.
- should
-
If a document or user agent conflicts with this
statement, undesirable results may occur in practice even though it
conforms to this specification.
- start-tag
-
Descriptive markup that identifies the start of an
element and specifies its generic identifier and attributes. [SGML]
- syntax-reference character set
-
A coded character set whose range
includes all characters used for markup; e.g. name characters and
delimiter characters.
- tag
-
Markup that delimits an element. A tag includes a name which
refers to an element declaration in the DTD, and may include
attributes.[SGML]
- text entity
-
A finite sequence of characters. A text entity
typically takes the form of a sequence of octets with some associated
character encoding scheme, transmitted over the network or stored in a
file.[SGML]
- typical
-
Typical processing is described for many elements. This
is not a mandatory part of the specification but is given as guidance
for designers and to help explain the uses for which the elements were
intended.
- URI
-
A Universal Resource Identifier is a formatted string that
serves as an identifier for a resource, typcally on the Internet. URIs
are used in HTML to identify the destination of hypertext links, the
source of in-line images, and the object of form actions. URIs in
common use include Uniform Resource Locators (URLs)[URL]
and Relative URLs[RELURL].
- user agent
-
A component of a distributed system that presents
an interface and processes requests on behalf of a user; for example,
a www browser or a mail user agent.
- WWW
-
The World-Wide Web is a hypertext-based, distributed
information system created by researchers at CERN in
Switzerland. Users may create, edit or browse hypertext
documents. `http://www.w3.org/'
