XSL-FO insert a blank line

I am using <fo:block/> to insert blank line. This does
not seem to work properly. As I am totally new to
xsl-fo, can anybody suggest me how to insert a blank
line?
<fo:static-content flow-name="xsl-region-after">
		</fo:block>
		<fo:block/>
		<fo:block/>
		<fo:block/>
		<fo:block/>
		<fo:block font-family="Helvetica" font-size="10pt"
			text-align="left">
			XYZ Corporation
		</fo:block>
	</fo:static-content>
