<root> Variable

This command is required. If not specified, an error occurs.

Indicates the root variable. A root variable defines the sequence of tokens, or domain pattern, as rule variables. Rule variables define the valid set of characters and the sequence in which those characters can occur in order to be considered a member of a domain pattern.

Example

<root> = <Title><GivenName><FamilyName>;

This command defines the domain pattern for a personal name that includes a title. Only personal names that include a title will match this domain pattern.

To use this command:

1. Position the cursor where you want the command inserted.
2. Double-click <root> in the Commands list.
3. Type the root expressions for the root tag. Make sure there is an equal sign separating <root> and the root expressions.
