In this example, you could make this a block

<TR BGCOLOR="white" ALIGN=LEFT><TH>Name</TH><TD>{NAME}</TD>
<!-- BEGIN bk_email -->
  <TR BGCOLOR="white" ALIGN=LEFT><TH>Email</TH><TD><FONT color="red">{EMAIL}</FONT></TD>
<!-- END bk_email -->
<!-- BEGIN bk_fax -->
  <TR BGCOLOR="white" ALIGN=LEFT><TH>Fax</TH><TD>{FAX}</TD>
<!-- END bk_fax -->

set_block this and zap it on demand. Logic does not belong
into Templates. It does belong into PHP.

You are able to construct examples where Template as it is now
breaks down. In this case you should ask youself if it is worth
to change Template to accomodate that case - in most cases it is
not, but Template is just the wrong tool for that job.
