How can I add line break into text that I am creating with XSLT?

I am trying to create text output from an xml file using xslt. It is actually an xslt that creates SQL code. Here is a part that outputs CREATE TABLE statements:

CREATE TABLE dbo.[<xsl:value-of select="@PhysicalName"/>] (
  <xsl:for-each select="EntityAttributes/EntityAttribute">
    <xsl:apply-templates select="Attributes/Attribute[@AttributeID = current()/@EntityAttributeID]"/> ...
  </xsl:for-each>)

I want to have a line break after the "(" in the first line but cannot manage to find out how to do so. Can anyone help?
