3 Questions about FOP.

I have a couple of questions about FO, but first some background. I am using
Cocoon2 and Tomcat for my programming. Xalan is also installed.

Question 1:

How can I position a document title so it is on a single page and centered
vertically? I tried the "vertical-align='middle'" attribute but it didn't
have any effect. 

My XSL template is:
		<xsl:template match="title">
			<fo:block font-size="28pt" 
				text-align="center" 
				font-weight="bold">
				<xsl:apply-templates/>
			</fo:block>
		</xsl:template>

Question 2:

How do I centre a table? When I use the "text-align='center'" in the
fo:block declaration before the able (see XSL below), the text in the table
gets centered but not the table itself. I want the equivalence of HTML's
"<center><table> .... </table></center>"

	<fo:block font-size="10pt" >
	<xsl:for-each select=".">
		<fo:table>
			....
	</fo:block>

Question 3:

The only way I could get a graphic to appear is by using "external-graphic".
Is there another way? Preferably, I would like to use relative links. Also,
how can I get my image to appear in the size it was created in and not
stretch to fill a page? I also have a linke below my image which I do not
know where it came form.

Here's my XSL:
<xsl:template match="graphic">
	<fo:block font-weight="bold">
		<xsl:value-of select="name"/>
	</fo:block>
	<fo:block
    text-align="center" 
    margin-top=".75in"
    page-break-after="always">
	   <fo:external-graphic>
	   <xsl:attribute
name="src">http://workstation/cocoon/development/_images/<xsl:value-of
select="location"/></xsl:attribute>
	   </fo:external-graphic>
</fo:block>
