No its not supported in any version - Struts only supports attributes
that are in the HTML 4 spec and has a policy of not adding non
standard attributes.

The tags were refactored in Struts 1.2.7 to make creating custom
implementations and adding additional attributes easier. So if you are
going to upgrade then this would be your only option. If you want to
do this in the form tag then something like the following:

public MyFormTag extends FormTag {
    protected void renderOtherAttributes(StringBuffer results) {
        renderAttribute(results, "autocomplete", "off");
    }
}

In the other form "input" tags the equivalent method is prepareOtherAttributes()

For  notes on upgrading and the issues you'll face then there are
upgrade notes on the wiki:
