<mm-group id="company_details">

The "where" Attribute
As can be seen from the preceding examples, the
output based on device type. It also can identify devices based on specific attributes.
The attribute can be used with the following tags:
where
•
<mm-include>
•
<mm-exclude>
•
<mm-img>
•
<mm-structure>
•
<mm-layout>
•
<mm-table-model>
Usage of the "where" Attribute
The conditional expressions following the
referenced device profile attributes. If the condition evaluates to true, then the content enclosed
by the tag will be added/excluded/manipulated for that device (depending on the tag's
functionality).
If the attribute does not evaluate to true, it will be ignored (except when
where
used). For example:
where="AttributeName==AttributeValue or AttributeName2==AttributeValue2"
Note: The "where" attribute quoted string must not contain line breaks.
The attribute:
