Attributes
Attributes are used to change properties of elements. Each element has a set of attributes that affect it, and each attribute can work differently for each element. Depending on the element, its value can be computed or simply verified also it can be internally stored or not.
If an element does not have a given attribute defined, this attribute will be inherited from its parent. Only a few attributes are not inherited: "TITLE", "VALUE", "ALIGNMENT", "X", "Y", "RASTERSIZE" and "SIZE".
