Braces {} within a property definition indicate a reference to the value of another property in the schema, as in the following example:
<RANGE>
<MIN TYPE="Inclusive">0</MIN>
<MAX TYPE="Inclusive">{maxOffset}</MAX>
<DEFAULT>0</DEFAULT>
</RANGE>
In the above example, {maxOffset} indicates that the maximum value allowed for the minOffset property must equal the value set for the maxOffset property. In this way, the software makes sure that the minOffset value does not exceed the maxOffset value.
Braces act as simple text replacements for property values and therefore have many applications in schema property definitions.
