Validating Code 103
5 If you need to validate something beyond the scope of the specifications selected
in the
Options > Settings Validation pane, use the other tabs in this dialog box.
Following is a description of what you can do on each tab:
•
Tags Require a tag, specify if a tag is case-sensitive, indicate if a tag has a
closing tag and if it is optional or required, add or remove a tag, add or remove
an allowed attribute for a tag, select a valid value for an attribute from a list of
available values, require an attribute, allow a required attribute to be absent,
and add or remove a
context for a tag (a tag in which the tag can be nested).
•
Values Add values, specific values or regular expressions, to the list of valid
values that you can specify for an attribute. The checkboxes on this tab allow
you to filter the list of values.
For information about regular expressions, see
“Using Regular Expressions”
on page 90 .
•
Versions Create a new family of languages, for example the XML language
MathML, and add versions to language families. A version inherits everything
from the parent language.
You can add tags to a new family on the Tags tab, or you can back up the
validator (.vtv) files in the \Extensions and \Extensions\TagDefs directories
and then modify them in the editor.
Caution
The changes you make on these tabs take effect immediately and cannot be
undone, even if you click Cancel. Be especially careful with the Remove buttons.
