CQ/AEM where are functions like 'cq5forms_showMgs()' defined?

Question

I noticed that CQ occasionally uses these javascript cq5forms functions and variables. I'm wondering where they are defined and how they work.

Specifically, I want to know where cq5forms_isEmpty() is defined. I'm trying to get the built in clientside validation to work, but the JavaScript console keeps giving a reference error that says cq5forms_isEmpty() is not defined.

Some other examples of these cq5forms function include the cq5forms_showMgs() function in clientvalidation.jsp for the built in password constraint:

...
if(last!=confirm) {
            cq5forms_showMsg(<%
                %>'<%= xssAPI.encodeForJSString(formId) %>',<%
                %>'<%= xssAPI.encodeForJSString(name) %>_confirm',<%
                %>'<%= xssAPI.encodeForJSString(ValidationHelper.getConstraintMessage(resource)) %>');
            return false; 
    }
...

And cq5forms_isArray() and cq5forms_regcheck() gets written out in FieldHelper.java:

    public static void writeClientRegexpText(...)
        ...
        out.write(id);
        out.write(";" +
                  "if ( cq5forms_isArray(obj)) { \n" +
                  "for(i=0;i<obj.length;i++) { \n" +
                  "if (!cq5forms_regcheck(obj[i].value, ");
        out.write(regexp);

        out.write(")) { \n" +"cq5forms_showMsg('");
        ...

If anyone could point me to where these are defined and how they are suppose to be used it would be much appreciated.

This javascript functions belong to the cq.forms clientlibrary. You can find the js code at the following location in crx /etc/clientlibs/foundation/form/form.js
