Unary Op

The ‘mo-unary’ is established in the first pass over inline-math, so we need to wait for the second pass with the following.

<..eliminate inline math narrative NO 2 ..>

<xsl:template match="span[
     (@class = ’inline-math’)
   and
     (count( <.math content element .> ) = 2)
   and
     (  child::mo[
           (@class = ’mo-unary’)
         and
           following-sibling::*[1]
           / self::mi
        ]
       or
        child::mi[
           following-sibling::*[1]
           [ (@class = ’MathClass-open-close’)
             and
             not(child::*[2]
                 / child::*[ not(self::BREAK) ]
                 / child::*[ not(self::BREAK) ] )
        ]  ]
     )
]" >
   <xsl:copy>
     <xsl:choose>
        <.when func on shallow arg .>
        <xsl:otherwise>
           <.unary op on short content .>
        </xsl:otherwise>
     </xsl:choose>
   </xsl:copy>
</xsl:template>

<..when func on shallow arg ..>

<xsl:when test="

    <xsl:attribute name="class">

    </xsl:attribute>
    <PROS PITCH="-5">

       <xsl:apply-templates
