Creating a tag definition file 203

You can create the definition file in one of the following ways:

• Write it manually.

• Create it from an existing tag definition file.

• Use the Tag Definitions Library dialog box to add a tag and edit the generated file.

The following sections describe how to define attribute categories

Defining attributes

The attributes block defines attributes inside the main tag block.

See ../VTML_Reference/attributes.htmlattributes/a in the VTML Reference for

syntax and usage information.

The attributes block can only contain attrib tags. The following example

demonstrates the definition of four tag attributes:

</attributes>

In most cases, features such as Tag Insight require more than just the names of the

attributes. You can use the

attrib tag to define the following attributes:

• Attribute value types

• Enumerated values for the

align attribute

The optional caption attribute specifies the form in which the option appears in the

drop-down lists, while the value attribute specifies the underlying value used by the

attribute.

See ../VTML_Reference/attrib.htmlattrib/a in the VTML Reference for syntax and

usage information.

Defining attribute categories

Use the attribcategories section to organize the attributes when viewed in Tag

Inspector. The attribcategories block can only contain attribgroup tags. The

following example shows four attribute category definitions.

<attribgroup name="appearance"

elements="background,bgproperties,leftmargin,,topmargin"/>

<attribgroup name="colors"

elements="bgcolor,vlink,alink,link,text"/>

<attribgroup name="misc"

elements="gizmo"/>

</attribcategories>

See ../VTML_Reference/attribgroup.htmlattribgroup/a in the VTML Reference for

syntax and usage information.
