*
* name - a textual name for this type. This name can be used to

* help - a textual string which describes the syntax of this type.
* When a parameter is filled out incorrectly on the CLI, this

*
* pattern - A regular expression which defines the syntax of the type.
*
* method - The means by which the pattern is interpreted.
*
* "regexp" [default] - A POSIX regular expression.
*
* "integer" - A numeric definition "min..max"
*
* "select" - A list of possible values.
* The syntax of the string is of the form:
* "valueOne(ONE) valueTwo(TWO) valueThree(THREE)"
* where the text before the parethesis defines the syntax
* that the user must use, and the value within the parenthesis
* is the result expanded as a parameter value.
*
* preprocess - An optional directive to process the value entered before
* validating it. This can greatly simplify the regular expressions
* needed to match case insensitive values.
*
* "none" [default] - do nothing
*
* "toupper" - before validation convert to uppercase.
*
* "tolower" - before validation convert to lowercase.

* <COMMAND> is used to define a command within the CLI.
*
* name - a textual name for this command. (This may contain
* spaces e.g. "display acl")
*
* help - a textual string which describes the purpose of the
* command.
*
* [view] - defines the view which will be transitioned to, on

* current view stays in scope.
*
* [viewid] - defined the new value of the ${VIEWID} variable to
* be used if a transition to a new view occurs. By default
* the viewid will retain it's current value.
*
* [access] - defines the user group/level to which execution of this
* command is restricted. By default there is no restriction.
* The exact interpretation of this field is dependant on the
* client of libclish but for example the clish and tclish
* applications map this to the UNIX user groups.
*
* [escape_chars] - defines the characters which will be escaped (e.g. \$) before
* being expanded as a variable. By default the following
* characters will be escaped `|$<>&()#
*
* [args] - defines a parameter name to be used to gather the rest of the
* command line after the formally defined parameters
* (PARAM elements). The formatting of this parameter is a raw
* string containing as many words as there are on the rest of the
* command line.
*
* [args_help] - a textual string which describes the purpose of the 'args'
* parameter. If the "args" attribute is given then this MUST be
* given also.
*
* [lock] - the boolean field that specify to lock lockfile while
* command execution or not. Default is true.

* name - a textual name for this parameter.
*
* help - a textual string which describes the purpose of the
* parameter.
*
* ptype - Reference to a PTYPE name. This parameter will be
* validated against the syntax specified for that type.
* The special value of "" indicates the parameter is a boolean flag.
* The verbatim presence of the texual name on the command line
* simply controls the conditional variable expansion for this
* parameter.
*
* [mode] - Parameter mode. It can be "common", "switch" or
* "subcommand".
*
* [prefix] - defines the prefix for an optional parameter. A prefix
* with this value on the command line will signify the presence
* of an additional argument which will be validated as the
* value of this parameter.
*
* [optional]- Specify whether parameter is optional. The allowed values
* is "true" or "false". It's false by default.
*
* [order] - Used only together with "optional=true" field.
* If order="true" then user can't enter previously declared
* optional parameters after current validated parameter.
* The allowed values is "true" or "false". It's false by default.
*
* [default] - defines a default value for a parameter. Any parameters
* at the end of command line which have default values need
* not explicitly be entered.
*
* [value] - defines the user's value for subcommand. If this option
* is defined the entered parameter will be compared to this
* value instead the "name" field. If this field is defined
* the mode of PARAM will be forced to "subcommand". The
* feature is implemented to support subcommands with the
* same names.
*
* [hidden] - define the visibility of the parameter while ${__line}
* and ${__params} auto variables expanding. The allowed values
* is "true" and "false".
*
* [test] - define the condition (see the description of 'test'
* utility) to process this parameter.
*
* [access] - access rights
