Answer 1

You probably have another file in your path that matches the naming criteria for a validator.

Answer 2

Most probably you are having trouble due to your "////" at this
///////////////////
<form name="DynaSMSRequestActionForm">
You should remove those from code and try again. Hope this helps.

Answer 3

if you see below example compare that with your xml file in that you missed <var-jstype> inside <var>
Please try this.
<field property="id" depends="intRange">
<arg key="id" resource="false" />
<arg key="${var:min}" resource="false" />
<arg key="${var:max}" resource="false" />
<var>
<var-name>min</var-name>
<var-value>10</var-value>
<var-jstype></var-jstype>
</var>
</field>
