the best place for this validation is in field_validate.pl, presumably by creating new MetaFields for each of these entries and keying on the new MetaField types.<o:p></o:p></span></p>

<p class="MsoNormal" style="text-autospace:none"><span lang="EN-US" style="font-family:"Tahoma",sans-serif;color:black">Is this standard practice? A brief search doesn't pull documentation or examples of subclassing new MetaFields.<o:p></o:p></span></p>
