21.4.2.24 rule (Rule)
This element allows for a rule to be specified which changes the value of an existing constraint.
[Example: Consider the following example of a rule in a DrawingML diagram:
<ruleLst>
<rule type="primFontSz" val="2" />
</ruleLst>
In this example a rule is being defined that shrinks the primary font size down to a lower limit of 2pt font when the text no longer fits correctly in the layout node. end example]

Attributes |
Description |
|---|---|
fact (Factor) |
Factor used in a reference constraint or a rule in order to modify a referenced value by the factor defined. [Example: Consider the following example of fact in use in a DrawingML diagram: In this example, the width for transition1 is being defined as one-tenth the width of node1. end example] The possible values for this attribute are defined by the W3C XML Schema double datatype. |
for (For) |
Specifies the axis of layout nodes to apply a constraint or rule to. [Example: Consider the following example of for in use in a DrawingML diagram: In this example, the for attribute is specifying that node1 is a child node to the current layout node. end example] The possible values for this attribute are defined by the ST_ConstraintRelationship simple type (§21.4.7.20). |
forName (For Name) |
Specifies the name of the layout node to apply a constraint or rule to. [Example: Consider the following example of forName in use in a DrawingML diagram: In this example, forName is specifying the layout node named transition1 for its reference. end example] The possible values for this attribute are defined by the W3C XML Schema string datatype. |
max (Max Value) |
Sets the maximum value for a constraint so rules can no longer increase the constraint beyond that value. The possible values for this attribute are defined by the W3C XML Schema double datatype. |
ptType (Data Point Type) |
Specifies the type of data point to select. The possible values for this attribute are defined by the ST_ElementType simple type (§21.4.7.27). |
type (Constraint Type) |
Specifies the constraint to apply to this layout node. [Example: Consider the following example of type in use in a DrawingML diagram: In this example, type is specifying the width attribute of transition1. end example] The possible values for this attribute are defined by the ST_ConstraintType simple type (§21.4.7.21). |
val (Value) |
Specifies an absolute value instead of reference another constraint. [Example: Consider the following example of forName in use in a DrawingML diagram: In this example, val is specifying the absolute value of the width of transition1. end example] The possible values for this attribute are defined by the W3C XML Schema double datatype. |
[Note: The W3C XML Schema definition of this element's content model (CT_NumericRule) is located in §A.5.3. end note]
