122 Chapter 7 Using Web Development Languages
• 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 when using the Remove
toolbutton.

To require an attribute for a tag:
1 Select Options > Settings > Validation and click Validator Settings.
2 In the Validator Configuration dialog box, click the Tags tab.
3 Expand a set of tags, for example HTML 4.0.
4 Expand a tag in the list.
5 Select the tag’s Required folder and click Add.
6 In the Required Attribute dialog box, enter the name of an existing attribute and
click OK.
If the attribute is not in the Attribute folder, add it to the Attribute folder and then
add it to the Required Attributes folder.
7 To remove a required attribute, select the attribute in the Required folder and
click Remove.
8 If you are done setting validator options, click OK.
9 Back in the Settings dialog box, click Apply.
To validate against the HTML 4.0 specification:
1In the Options > Settings > Validation pane, select HTML 4.0.
2 Click Validator Settings.
3 In the Validator Configuration dialog box, on the Options tab, in the Report box,
select every type of error except CFML Compiler Errors.
4 In the Other box, select the options to check for quotes in text and report special
characters.
Checking for quotes ensures that each quotation mark is followed by another of
the same type (' or "). Reporting special characters catches errors like having
&
instead of & in the HTML.
5 On the Tags tab, expand the HTML 4.0 node and select the noframes node.
