Expression Components

Each expression consists of an Element, an Attribute and a Value.

Keywords are used for Elements and can be used for Attributes and Values, all keywords are prefixed by ‘@'.

Element keywords may be:

• @general which refers to the clash

• @element-1 which refers to one of the clashing elements

• @element-2 which refers to the other element.

  Note:
  No particular order is implied and there is no relationship to the elements 1 & 2 shown on the Clash Report.

Attribute may be a Keyword related to the Item, or may be any Attribute, for example SHOP, or NAME .

Value may be selected from a list-of-values related to the given attribute, or a Regular Expression, (Refer to Notes on Wildcards) or a Keyword (Refer to Expression Syntax).

Note:
The rules are formed by logical 'AND' operators between the expressions. There is no facility for logical 'OR' operators.
