## Usage

If you want to use additional parameters in your `s:a` the best practice is to use a `s:url` to create your url and then leverage this url into your `s:a` tag. This is done by creating a `s:url` and specifying an `var` attribute. Like `testUrlId` in this example. Then in the `s:a` tag reference this id in the href attribute via `%{testUrlId}`

    <s:url var="testUrlId" namespace="/subscriber" action="customField" method="delete">
        <s:param name="customFieldDefinition.id" value="${id}"/>
    </s:url>

    <s:a errorText="Sorry your request had an error." preInvokeJS="confirm('Are you sure you want to delete this item?')" href="%{testUrlId}">
        <img src="<s:url value="/images/delete.gif"/>" border="none"/>
    </s:a>

    <img xsrc="<s:url value="/images/delete.gif"/>" border="none"/>

    <s:a><img xsrc="<s:url value="/images/delete.gif"/>" border="none"/></s:a>
