/**
* Represents a property (meta-information) mapped to a VFS resource.
*
* A property is an object that contains three string values: a name, a property value which is mapped
* to the structure record of a resource, and a property value which is mapped to the resource
* record of a resource. A property object is valid if it has both values or just one value set.
* Each property needs at least a name and one value set.
*
* A property value mapped to the structure record of a resource is significant for a single
* resource (sibling). A property value mapped to the resource record of a resource is significant
* for all siblings of a resource record. This is possible by getting the "compound value"
* (see {@link #getValue()}) of a property in case a property object has both values set. The compound
* value of a property object is the value mapped to the structure record, because it's structure
* value is more significant than it's resource value. This allows to set a property only one time
* on the resource record, and the property takes effect on all siblings of this resource record.
*
* The ID of the structure or resource record where a property value is mapped to is represented by
* the "PROPERTY_MAPPING_ID" table attribute in the database. The "PROPERTY_MAPPING_TYPE" table
* attribute (see {@link #STRUCTURE_RECORD_MAPPING} and {@link #RESOURCE_RECORD_MAPPING})
* determines whether the value of the "PROPERTY_MAPPING_ID" attribute of the current row is
* a structure or resource record ID.
*
* Property objects are written to the database using {@link org.opencms.file.CmsObject#writePropertyObject(String, CmsProperty)}
* or {@link org.opencms.file.CmsObject#writePropertyObjects(String, List)}, no matter
* whether you want to save a new (non-existing) property, update an existing property, or delete an
* existing property. To delete a property you would write a property object with either the
* structure and/or resource record values set to {@link #DELETE_VALUE} to indicate that a
* property value should be deleted in the database. Set property values to null if they should
* remain unchanged in the database when a property object is written. As for example you want to
* update just the structure value of a property, you would set the structure value to the new string,
* and the resource value to null (which is already the case by default).
*
* Use {@link #setAutoCreatePropertyDefinition(boolean)} to set a boolean flag whether a missing property
* definition should be created implicitly for a resource type when a property is written to the database.
* The default value for this flag is false. Thus, you receive a CmsException if you try
* to write a property of a resource with a resource type which lacks a property definition for
* this resource type. It is not a good style to set {@link #setAutoCreatePropertyDefinition(boolean)}
* on true to make writing properties to the database work in any case, because then you will loose
* control about which resource types support which property definitions.
*
