11.12 HTML/XML Fields

11.12.1 General

Fields are a proprietary construct using structured SGML comments to convey information about a section of the document or some specified attribute of the content of the document. Fields are a defined method of adding information such as section numbering, text includes and other information that is inert to the reader.

Fields are structured both internally and externally like CSS and HTML. Field properties are specified in the form of property-value pairs like CSS declarations and field elements are like HTML in that they can have open and close elements. 

This section provides a series of functions to access and change field information via a Field Object. the purpose is to allow for script field support. This section does not discuss how fields operate in the application’s HTML environment. See the HTML Field Reference and the associated application User Manual for information regarding field specifications and use.

11.12.2 Field Structure

Field structure is as follows:

<!-- Field: Name; Param1: Value1; Param2: Value2; Param3: Value3; .... -->

Where:

<!-- data -->

Is an HTML comment as a container for a field.

Field: Name

The first item must be ‘Field:’ with a known name. Names can be preceded by a slash ‘/’ to denote a closing field.

Param: Value

A series of known parameter names and values. Value data must be encoded in URL fashion.

Most fields have both open and close pseudo tags. For example:

<!-- Field: Sequence; Type: Legal -->1.1.2<!-- Field: /Sequence -->

Closing fields do not have parameters.
