f:facet do not render its inner HTML tags

Insert next source example code into the page:

<h:panelGrid
columns="2" border="5" width="250"
rules="all" frame="above"
cellpadding="4" cellspacing="6"
bgcolor="silver"
style="COLOR: #ff0080; BACKGROUND-COLOR: #ffff00; TEXT-DECORATION: underline; FONT-STYLE: italic; FONT-WEIGHT: bold; FONT-SIZE: xx-large; FONT-FAMILY: 'Arial Black';"
styleClass=""
captionClass="myStyle0"
columnClasses="" rowClasses=""
headerClass="" footerClass="" >
<f:facet name="footer">
<p>sdlfsd</p>
<p>dsfjal</p>
<input type="button">fsdadf</input>
gkhadjksfg
</f:facet>
<h:outputText value="begin"/>
</h:panelGrid>

VPE doesn't render usuall html tags and simple text, but browsers do it. <f:facet> can content only one UIComponent for JSF and RichFaces components.
