I want to create anchor tags in my form template that contain widget

This produces the following error:
The value of attribute "href" associated with an element type "a" must 
not contain the '<' character

indeed, the result of what you typed doesn't pass the xml wellformedness 
test

Is there a way to do this within the template itself of do I need to add 
an xslt transform and use  <xsl:attribute>?

'fraid so.
here is what i recently did for showing a mail-address value as a 
mailto: -link

in the template: you add
<ft:widget id="email"><fi:styling type="email" /></ft:widget>
plus you provide your own field-styling xslt that
1/ inherits from the existing styling by importing
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                xmlns:fi="http://apache.org/cocoon/forms/1.0#instance";
                exclude-result-prefixes="fi">
  <xsl:import
href="context://samples/blocks/forms/resources/forms-advanced-field-styling.xsl" 
/>

and
2/ provide custom styling for these email-output styles
  <!--
     | this adds a fi:styling type="email" to widgets of type output
     | it will produce a mailto: href around them
     -->
  <xsl:template match="fi:output[fi:styling/@type='email']">
    <a href="mailto:{./fi:value}";><xsl:value-of select="./fi:value"/></a>
  </xsl:template>
(notice: the above uses the {} shorthand notation over the more puristic 
<xsl:attribute> but it pretty much boils down to the same thing

HTH,
