Here are a couple of examples. The first has no conditions on the template. You'll notice it is fairly simple.
<mos:tmpl name="head">
<h1>{TEST_HEAD} {LIC_CLASS_NAME}</h1>
<mos:tmpl src="hr_red.html" parse="on" />
<form action="index.php" method="post">
</mos:tmpl>
<mos:tmpl name="questions">
<mos:tmpl name="question">
<p>{TEXT}<br />
<mos:tmpl name="answers">
<input type="radio" name="ans[{KEY}]" value="{LETTER}">
{LETTER}. {TEXT}<br />
</mos:tmpl>
</p>
<mos:var name="image_src" copyfrom="IMAGE" modifier="HTML_Img" title="Image"/>
<mos:tmpl src="hr_red.html" parse="on" />
</mos:tmpl>
</mos:tmpl>
<mos:tmpl name="foot">
<input type="submit" name="submit" value="{GRADE_BUTTON}">
<input type="hidden" name="option" value="{OPTION}">
<input type="hidden" name="task" value="grade">
<input type="hidden" name="Itemid" value="{ITEMID}">
<input type="hidden" name="element" value="{ELEMENT}">
<input type="hidden" name="count" value="{COUNT}">
</form>
<p> </p>
</mos:tmpl>
The next template has multiple conditions. Parts need to be hidden based on whether a user is logged in or not. You'll notice how complex the template starts to get. Some of the html almost gets lost in the template code.
<mos:tmpl name="main">
<table class="contentpane" cellspacing="2px" cellpadding="3px" style="border: 1px solid;">
<tr style="color: #000000; font-size: 1.1em; text-align: center; border: 1px solid #ffffff; background-color: #cccccc"class="contentheading">
<th>Time Added</th>
<th>Buy/Sell</th>
<th>Ecurrency</th>
<th>Amount</th>
<th>Rate</th>
<th>Buyer/Seller Messages</th>
<mos:tmpl name="tablehead" type="simplecondition" requiredvars="main.uid">
<th>Add Buy Or Sell eCurrency</th>
</mos:tmpl>
</tr>
<mos:tmpl name="row">
<tr style="text-align: center; vertical-align: middle; border: 1px solid #ffffff; background-color: #f0f0f0">
<td nowrap>{ROW_CREATED}</td>
<td>{ROW_TRANSACTION}</td>
<td>{ROW_CURRENCY}</td>
<td>{ROW_AMOUNT}</td>
<td>{ROW_RATE}</td>
<td style="text-align: left"><a href="mailto:{ROW_EMAIL}">{ROW_USERNAME}</a>
<mos:tmpl type="simplecondition" requiredvars="row_image" varscope="row">
<a href="{ROW_EDITLINK}" alt = "Edit"><img src="{ROW_IMAGE}" alt="Edit Image" style="border:0"/></a>
</mos:tmpl>
<br />{ROW_MESSAGE}
</td>
<mos:tmpl name="tablecondition" type="simplecondition" requiredvars="main.uid">
<mos:tmpl name="table" type="condition" conditionvar="row.row_created">
<mos:sub condition="__first">
<td rowspan="{COUNT}">
<div style="text-align: left">
<table style="border: solid 1px #000000; float: right">
<mos:tmpl name="edit" type="condition" conditionvar="editrow_id" varscope="table">
<mos:sub condition="__default">
<tr>
<td>Record Id:
</td>
<td>{EDITROW_ID}
</td>
</tr>
<tr>
<td>Username:
</td>
<td>{EDITROW_USERNAME}
</td>
</tr>
</mos:sub>
<mos:sub condition="0" />
</mos:tmpl>
<tr>
<td>Buy/Sell:
</td>
<td>{SELECT_TRANS}
</td>
</tr>
<tr>
<td>eCurrency:
</td>
<td>{SELECT_CUR}
</td>
</tr>
<tr>
<td>Amount:
</td>
<td><input type="text" name="amount" class="inputbox" size="4" value="{EDITROW_AMOUNT}" />
</td>

<tr>

<td><input type="text" name="rate" class="inputbox" size="4" value="{EDITROW_RATE}" />
</td>
</tr>
<tr>
<td colspan="2">Additional Message:<br />
<textarea name="message" class="inputbox" cols="30" rows="7">{EDITROW_MESSAGE}</textarea>
</td>
</tr>
</table>
</div>
</td>
</mos:sub>
</mos:tmpl>
</mos:tmpl>
</tr>
</mos:tmpl>
</table>
<input type ="hidden" name="option" value="{OPTION}">
<input type ="hidden" name="task" value="{TASK}">
<input type ="hidden" name="Itemid" value="{ITEMID}">
</mos:tmpl>
Now remember, I'm still going through the learning curve. There may be some better methods I haven't yet discovered. But given the limited patTemplate docs this is the best I've been able to come up with.
.
I think that you have to rewrite the code of the modules and components to work with patTemplate. Correct me if I'm wrong
