<xsl:template match="*" name="fullNameWorker" mode="fullName">
         <xsl:if test=".!=/">
             <xsl:apply-templates select=".." mode="fullName"/>
             <xsl:if test="..!=/">.</xsl:if>

Never use != to compare node identity. It can be very expensive and it gives
the wrong answer. For example if your document is

<doc><subdoc>
    ...
  </subdoc></doc>

then doc and subdoc both compare equal to "/", and if the document is 100Mb
in size then you will be comparing some very long strings to prove it.

In 2.0, use "is". In 1.0, use generate-id(A)=generate-id(B).

     <xsl:template match="*" name="fullNameWorker" mode="fullName">
        <xsl:if test="generate-id(.)!=generate-id(/)">
            <xsl:apply-templates select=".." mode="fullName"/>
            <xsl:if test="generate-id(..)!=generate-id(/)">.</xsl:if>
            <xsl:value-of select="@name"/>
        </xsl:if>
     </xsl:template>

    <xsl:template name="fullName">
        <fullName>
            <xsl:call-template name="fullNameWorker" />
        </fullName >
    </xsl:template>

    <xsl:template match="*" name="fullNameWorker" mode="fullName">
        <xsl:if test=".!=/">
            <xsl:apply-templates select=".." mode="fullName"/>
            <xsl:if test="..!=/">.</xsl:if>
            <xsl:value-of select="@name"/>
        </xsl:if>
    </xsl:template>

    <xsl:template match="*">
        <myNewNode>
		<xsl:call-template name="fullName">
	</myNewNode>
    </xsl:template>
