■ String-delimited tags

String-delimited tags start with one string and end with another string. They are like

empty HTML tags (such as

img) in that they don’t surround content and don’t have

closing tags. If the

happy tag were a string-delimited tag, the tag specification would

include the

start_string and end_string attributes. An ASP tag is a string-delimited

tag; it starts with the string

<% and ends with the string %>, and it has no closing tag.

The following information describes the attributes and valid values for the

tagspec tag.

Attributes marked with an asterisk (*) are ignored for string-delimited tags. Optional

attributes are marked in the attribute lists with curly braces (

{}); all attributes not marked

with curly braces are required.

Description

Provides information about a third-party tag.

Attributes

tag_name, {tag_type}, {render_contents}, {content_model}, {start_string},

{end_string}, {detect_in_attribute}, {parse_attributes}, icon,

icon_width, icon_height, {equivalent_tag}, {is_visual}, {server_model}

■ tag_name is the name of the custom tag. For string-delimited tags, tag_name is used only

to determine whether a given Property inspector can be used for the tag. If the first line of

the Property inspector contains this tag name with an asterisk on each side, the inspector

can be used for tags of this type. For example, the tag name for ASP code is

ASP. Property

inspectors that can examine ASP code should have

*ASP* on the first line. For

information on the Property inspector API, see

Chapter 12, “Property Inspectors,” on

page 279

■ tag_type determines whether the tag is empty (as the img tag is), or whether it contains

anything between its opening and closing tags (as the

code tag does). This attribute is

required for normal (nonstring-delimited) tags. It’s ignored for string-delimited tags

because they’re always empty. Valid values are

"empty" and "nonempty".

■ render_contents determines whether the contents of the tag should appear in the

Design view or whether the specified icon should appear instead. This attribute is required

for nonempty tags and is ignored for empty tags. (Empty tags have no content.) This

attribute applies only to tags that appear outside attributes. The contents of tags that

appear inside the values of attributes of other tags are not rendered. Valid values are

"true" and "false".
