Use generate-id(), unless you want the ID to mean something and not just be
unique within that single transformation process.

Say the id of B1 is X

>          </A1>
> </A-Group>

How do you know this is X without marking it up?

	<xsl:key name="group" match="*" use="substring(name(), 1, 1)"/>

	<xsl:template match="/">
		<xsl:for-each select="descendant::*[generate-id() = generate-id(key('group',
substring(name(), 1, 1)))]">
			<xsl:variable name="group" select="substring(name(), 1, 1)"/>
			<xsl:element name="{$group}-Group">
				<xsl:for-each select="key('group', $group)">
					<xsl:copy>
						<xsl:attribute name="id">
							<xsl:value-of select="generate-id()"/>
						</xsl:attribute>
						<xsl:for-each select="*">
							<reference id="{generate-id()}"/>
						</xsl:for-each>
					</xsl:copy>
				</xsl:for-each>
			</xsl:element>
		</xsl:for-each>
	</xsl:template>

Cheers,
