This short and simple transformation (has minimum number of templates and doesn't use any explicit XSLT conditional instructions, no xsl:attribute or priority attributes):

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xsi="3" xsi:schemalocation="4">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="node()[not(self::*)]|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="*">
  <xsl:element name="{name()}" namespace="1.2">
   <xsl:copy-of select=
   "document('')/*[not(current()/../..)]
                        /@xsi:schemalocation"/>
   <xsl:apply-templates select="@*|node()"/>
  </xsl:element>
 </xsl:template>
</xsl:stylesheet>

when applied on the provided XML document:

<Employees>
    <employee>
        <dept>1</dept>
        <sec></sec>
    </employee>
    <employee>
        <dept>2</dept>
        <sec></sec>
    </employee>
</Employees>

produces the wanted, correct result:

<Employees xmlns="1.2" xmlns:xsi="3" xsi:schemalocation="4">
   <employee>
      <dept>1</dept>
      <sec/>
   </employee>
   <employee>
      <dept>2</dept>
      <sec/>
   </employee>
</Employees>

Here's how you do it:

<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xsi="3">

  <xsl:output indent="yes"/>

    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="*" priority="2">
        <xsl:element name="{local-name()}" namespace="1.2">
            <xsl:if test="self::Employees">
                <xsl:attribute name="xsi:schemalocation">4</xsl:attribute>          
            </xsl:if>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

You apply the identity transformation as a default and then override it for elements to give them a new namespace as well as a special attribute for the Employees node. I chose to add an if statement but you also can move that logic into another template that matches Employees. I just didn't want to repeat the whole xsl:element thing twice. Matter of taste really.

When I apply this transformation to your input document I end up with:

<Employees xmlns="1.2" xmlns:xsi="3" xsi:schemalocation="4">
    <employee>
        <dept>1</dept>
        <sec/>
    </employee>
    <employee>
        <dept>2</dept>
        <sec/>
    </employee>
</Employees>

You had the xmlns="" in your result likely because you weren't recreating all elements in that new namespace. Also, to be able to add the xsi:schemalocation attribute you need to declare the xsi namespace on the transformation document.
