About Singleton Tags and Multipart Tags

Singleton and multipart tags are part of the basic vocabulary of SGML (Standard Generalized Markup Language). This topic only describes them as they pertain to Siebel CRM, which uses singleton and multipart tags in the typical way.

A singleton element is a tag that includes a slash that indicates the end of the tag. It occurs in the same tag as the tag name. A singleton tag does not include child elements. The following is an example of a singleton tag:

<div od-type="pageitem" od-name="value"/>

The following is an example of a multipart tag. It does not include a slash at the end of the tag:

<div od-type="control" id="1" property="formattedHTML">

...HTML here...

<!--od section control close->

</div>

About the This Tag

A this tag is a type of Siebel tag that you can use if you must use a multipart tag but reference the control that the Siebel Web Engine creates at a location other than at the beginning or end of the tag. The following code includes an example of a this tag:

<div od-type="control" id="1">

...HTML here...

<div od-property="formattedHTML"/>

<!--od section control close->

</div>

The <div od-property> tag is an alias for the nearest enclosing Siebel context. You can enclose the <div od-type="xxx"> element to create this context. For example, Siebel CRM commonly includes the <div od-property> tag in a multipart <div od-type="control"> element. In this situation, the <div od-property> tag is an alias for the control. You use it to display properties of the control. In some situations, the context is less direct. For example, if Siebel CRM includes a <div od-property> element in an applet template file, and if the <div od-property> tag is not in any <div od-type="control"> tag, then it is an alias for the applet and you can use it to display properties of the applet.
