Auxiliary information to allow a printing application to use
the channel for data submission to the printer.  An application
capable of using a specific PrtChannelType should be able to use
the combined information from the prtChannelInformation and
other channel and interface group objects to 'bootstrap' its use
of the channel.  prtChannelInformation is not intended to
provide a general channel description, nor to provide
information that is available once the channel is in use. 
The encoding and interpretation of the prtChannelInformation
object is specific to channel type.  The description of each
PrtChannelType enum value for which prtChannelInformation is
defined specifies the appropriate encoding and interpretation,
including interaction with other objects.  For channel types
that do not specify a prtChannelInformation value, its value
shall be null (0 length).  
When a new PrtChannelType enumeration value is registered, its
accompanying description must specify the encoding and
interpretation of the prtChannelInformation value for the
channel type.  prtChannelInformation semantics for an existing
PrtChannelType may be added or amended in the same manner as
described in section 2.4.1 for type 2 enumeration values.
The prtChannelInformation specifies values for a collection of
channel attributes, represented as text according to the
following rules: 
 1. The prtChannelInformation is coded in the NVT ASCII
    character set.  It is not affected by localization. 
 2. The prtChannelInformation is a list of entries representing
    the attribute values.  Each entry consists of the following
    items, in order: 
     a. a keyword, composed of alphabetic characters (A-Z,
        a-z), that identifies a channel attribute,
     b. an Equals Sign (=) to delimit the keyword,
     c. a data value, consisting of NVT ASCII graphics
        characters (codes 32-126),
     d. a Line Feed character (code 10) to delimit the data
        value. 
    No other characters shall be present. 
    Keywords are case-sensitive.  Conventionally, keywords are
    capitalized (including each word of a multi-word keyword),
    and, since they occupy space in the prtChannelInformation,
    they are kept short. 
 3. If a channel attribute has multiple values, it is
    represented by multiple entries with the same keyword, each
    specifying one value.  Otherwise, there shall be at most
    one entry for each attribute. 
 4. By default, entries may appear in any order.  If there are
    ordering constraints for particular entries, these must be
    specified in their definitions. 
 5. The prtChannelInformation value may represent information
    that is not normally coded in textual form, or that is coded
    in a character set other than NVT ASCII.  In these cases,
    whatever symbolic representation is conventionally used for
    the information should be used for encoding the
    prtChannelInformation.  (For instance, a binary port value
    might be represented as a decimal number, Unicode would
    be represented in UTF-8 format.) 
 6. For each PrtChannelType for which prtChannelInformation
    entries are defined, the descriptive text associated with the
    PrtChannelType enumeration value shall specify the following
    information for each entry: 
    Title:          Brief description phrase, e.g.: 'Port name',
                    'Service Name',
    Keyword:        The keyword value, eg: 'Port', 'Service'
    Syntax:         The encoding of the entry value, if it
                    cannot be directly represented by NVT ASCII,
    Status:         'Mandatory', 'Optional', or 'Conditionally
                    Mandatory',
    Multiplicity:   'Single' or 'Multiple', to indicate whether
                    the entry may be present multiple times,
    Description:    Description of the use of the entry, other
                    information required to complete the
                    definition (e.g.: ordering contstraints,
                    interactions between entries). 
Applications that interpret prtChannelInformation should ignore
unrecognized entries, so they are not affected if new entry
types are added.

        Additional information:
        IIO-based channels provide their own values for this
        object.
