File: Data.xml
<poem year="1667" type="epic">
  <verse>line 3</verse>
  <verse>line 4</verse>
</poem>

File: Transform.xslt
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="1.0">
  <xsl:output omit-xml-declaration="yes" />
  <xsl:attribute-set name="lineAttrs">
    <xsl:attribute name="status">done</xsl:attribute>
    <xsl:attribute name="hue">
    <xsl:value-of select="@color" />
  </xsl:attribute>
    <xsl:attribute name="number">
    <xsl:value-of select="amount" />
  </xsl:attribute>
    <xsl:attribute name="sourceElement">
    <xsl:text>src</xsl:text><xsl:value-of select="generate-id()" />
  </xsl:attribute>
  </xsl:attribute-set>
  <xsl:template match="verse">
    <xsl:element name="line" use-attribute-sets="lineAttrs">
      <xsl:attribute name="author">BD</xsl:attribute>
      <xsl:attribute name="hue">NO COLOR</xsl:attribute>
      <xsl:apply-templates />
    </xsl:element>
  </xsl:template>
</xsl:stylesheet>
Output:

  <line status="done" hue="NO COLOR" number="" sourceElement="srcd2e3" author="BD">line 3</line>
  <line status="done" hue="NO COLOR" number="" sourceElement="srcd2e6" author="BD">line 4</line>

Create two attribute sets

File: Data.xml
<?xml version="1.0"?>
<?xml-stylesheet href="Transform.xslt" type="text/xsl"?>
<message>test</message>
File: Transform.xslt
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" />
  <xsl:attribute-set name="para">
    <xsl:attribute name="doc:style"
      namespace="http://www.wbex.ru/documents">classic</xsl:attribute>
  </xsl:attribute-set>
  <xsl:attribute-set name="paragraph">
    <xsl:attribute name="priority">medium</xsl:attribute>
    <xsl:attribute name="date">2003-09-23</xsl:attribute>
  </xsl:attribute-set>
  <xsl:template match="/">
    <xsl:element name="paragraph" use-attribute-sets="para">
      <xsl:apply-templates />
    </xsl:element>
  </xsl:template>
</xsl:stylesheet>
Output:
<?xml version="1.0" encoding="UTF-8"?>
<paragraph xmlns:doc="http://www.wbex.ru/documents" doc:style="classic">test</paragraph>

Define and use attribute-set

File: Data.xml

<?xml version="1.0"?>
<countries>
  <country name="France" />
  <country name="Germany" />
  <country name="Israel" />
  <country name="Japan" />
  <country name="Poland" />
  <country name="United States" selected="yes" />
  <country name="Venezuela" />
</countries>
File: Transform.xslt
<?xml version="1.0"?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="2.0">
  <xsl:strip-space elements="*" />
  <xsl:output method="xml" indent="yes" />
  <xsl:template match="*">
    <xsl:copy>
      <xsl:apply-templates />
    </xsl:copy>
  </xsl:template>
  <xsl:template match="line">
    <xsl:copy use-attribute-sets="sequence">
      <xsl:apply-templates />
    </xsl:copy>
  </xsl:template>
  <xsl:attribute-set name="sequence">
    <xsl:attribute name="number" select="position()" />
    <xsl:attribute name="of" select="last()" />
  </xsl:attribute-set>
</xsl:transform>
Output:
<?xml version="1.0" encoding="UTF-8"?>
<countries>
   <country/>
   <country/>
   <country/>
   <country/>
   <country/>
   <country/>
   <country/>
</countries>
