XSM User's Guide 227

Annotation E A Description

key-fields 9— Allows specification of columns that

uniquely identify the rows in a table

limit-field 99Allows limiting the values that are returned

on the basis of a limiting value

limit-value 99Allows limiting the values that are returned

on the basis of a limiting value

mapped 99Allows schema items to be excluded from

the result

max-depth 9— Allows you to specify depth in recursive

relationships that are specified in the

schema

overflow-field 9— Identifies the database column that contains

the overflow data

relation 9— Maps an XML item to a database table

relationship-

child

9—Specifies an element as the child table in a

reference (To define only in the child

element property sheet)

relationship-

child-key

9—Specifies an attribute as the foreign key of a

child table in a reference (To define only in

the child element property sheet)

relationship-

parent

9—Specifies an element as the parent table in

a reference (To define only in the child

element property sheet)

relationship-

parent-key

9—Specifies an attribute as the primary key of

a parent table in a reference (To define only

in the child element property sheet)

use-cdata 9— Allows specifying CDATA sections to be

used for certain elements in the XML

document

prefix — 9Creates valid XML ID, IDREF, and

IDREFS. Prepends the values of ID,

IDREF, and IDREFS with a string

3 Click OK.4 Repeat steps 1 to 3 for each element or attribute you want to map with adatabase table or column, or for which you want to define extraannotations.
