Tag libraries and editors

The taglibrary tag groups one or more tags into a tag library. When you import tags or create a new set of tags, you

can group them into tag libraries. Typically, a

taglibrary grouping corresponds to a set of tags that are defined in a

JavaServer Pages (JSP) TLD file, an XML document type definition (DTD) file, an ASP.NET namespace, or some other

logical grouping.

The following table lists the taglibrary attributes:

The following table lists tagref attributes:

Because the tagref.prefix attribute can override the taglibrary.prefix attribute, the relationship between the

two attributes can be confusing. The following table shows the relationship between the

taglibrary.prefix and

tagref.prefix attributes:

Attribute Description Mandatory/optional

taglibrary.name Used to refer to the tag library in the UI. Mandatory

taglibrary.doctypes Indicates the document types for which this library is active.

When the library is active, library tags appear in the code hints

menu. Not all tag libraries can be active at the same time because

name conflicts can occur (for example, HTML and WML files are

incompatible).

Mandatory

taglibrary.prefix When specified, tags within the tag library have the form

taglibrary.prefix + tagref.name. For example, if the

taglibrary.prefix is "<jrun:" and the tagref.name is

"if", then the tag is of the form "<jrun:if". This can be

overridden for a particular tag.

Optional

taglibrary.servermodel If the tags in the tag library execute on an application server, the

servermodel attribute identifies the server model of the tag. If

the tags are client-side tags (not server-side tags), the

servermodel attribute is omitted. The servermodel attribute

is also used for Check Target Browsers.

Optional

taglibrary.id This can be any string that is different from the taglibrary.ID

attributes of other tag libraries in the file. The Extension Manager

uses the ID attribute, so the MXP files can insert a new

taglibrary and the tags files into the TagLibraries.vtm file.

Optional

taglibrary.tagchooser A relative path to the TagChooser.xml file that is associated with

this tag library.

Optional

Attribute Description Mandatory/optional

tagref.name Used to refer to the tag in the UI. Mandatory

tagref.prefix Specifies how the tag appears in Code view. When used, the

tagref.prefix attribute determines the prefix of the current

tag. When the attribute is defined, it overrides the value specified

for the

taglibrary.prefix attribute.

Optional

tagref.file References the VTML file for the tag. Optional

Is the taglibrary.prefix defined? Is the tagref.prefix defined? Resulting tag prefix

No No '<' + tagref.name

Yes No taglibrary.prefix + tagref.name

No Yes tagref.prefix

Yes Yes tagref.prefix
