Distributed Attributes Schema

A distributed attribute schema is headed with a DSXSCH element. Currently there is no particular support or use of multiple schemas but to organize distributed attributes in groups of definitions.

Distributed Attributes Schema Definition Element, DSXSCH

The DSXSCH defines a distributed attribute schema the vital attribute is the DEFHOM that may contain a reference to a schema default DSXHOM element. The DSXSCH element can have DSXOWN as members.


Attribute Name	Type	Usage
NAME	Text	Standard
DESC	Text	Standard
DEFHOM	Ref to DSXHOM	Identifies the default home selector for this schema

Binder Definition Element, DSXOWN

The DSXOWN defines the element types that may have the defined set of distributed attributes. One DSXOWN may define one or more element types as defined by the ELEL attribute. It also contains an optional reference to a binder default DSXHOM element, that DSXHOM overrides any DSXHOM definition on the DSXSCH level. The DSXOWN element can have DSXMBR as members.


Attribute Name	Type	Usage
NAME	Text	Standard
DESC	Text	Standard
DEFHOM	Reference to DSXHOM	Identifies the default home selector for the binder. Overrides any definition on schema level.
ELEL	Element types list	Defines the element types that may have distributed attribute types bound to them

Distributed Attribute Definition Element, DSXMBR

The DSXMBR defines the element types to be used as distributed attributes. One DSXMBR may define one or more element types as defined by the ELEL attribute. The element types must be UDETs based on the XPITEM element type. It also contains an optional reference to a distributed attribute default home DSXHOM element, that DSXHOM overrides any definition on the DSXOWN level.


Attribute Name	Type	Usage
NAME	Text	Standard
DESC	Text	Standard
DEFHOM	Reference to DSXHOM	Identifies the default home selector for the distributed element types defined in this definition
AUTCRE	Logical	Auto-create. The distributed element is automatically created if it doesn't exist at a modification operation.
ELEL	Element types list	Defines the element types that represents the distributed attribute types
CARD	Integer array [2]	Min and Max cardinality of the distributed attributes. (Note, only the Max Cardinality is currently effective)
