/** A Versit property parameter. 

A property parameter consists of a name and optionally a value, both in descriptor 

form. Parser properties (class CParserProperty) may own one or more property 

parameters.

Note:

The private parameter name and value members are stored as narrow (8-bit) 

rather than 16-bit Unicode descriptors.

However, certain member functions take or return a Unicode value, 

for the purpose of backwards compatibility. In this case a simple conversion 

takes place: this ignores the top 8 bits (for Unicode -> Narrow) or adds zero 

for the top 8-bits (for Narrow->Unicode).

/** A vCard or vCalendar property.

A property consists of a name, an optional value and one or more optional

The name, value and parameters are initialised on construction.

Versit properties have the general form:

Property Name (; Property Parameter Name(=Property Parameter Value)* : Property 

Value)

where items in brackets are optional and * indicates that the item may be 

repeated. 

For instance, TEL; HOME; ENCODING=QUOTED-PRINTABLE; CHARSET=US-ASCII : 01234 567890

Here, TEL is the property name; HOME, ENCODING and CHARSET are property parameter 

names; QUOTED-PRINTABLE and US-ASCII are property parameter values. The component 

following the colon is the property value.

Properties also have a name UID, which set during internalisation of a property 

and used only during internalisation. It is set by SetNameUid() and is used 

to allow number comparisons during internalisation. This provides a faster 

alternative to string comparisons when checking a property to see if it is 

a significant one (e.g. a begin or binary property). This is the only use 

of the name UID: it is not used during externalisation of a property.

Note that grouped properties are supported by the derived class, CParserGroupedProperty. 

The vCalender parser does not have property groups, and so stores all properties 

using this base class, whereas the vCard parser stores all properties using 

CParserGroupedProperty.
