XSL choose or if??

I have the following tag which is fine when there's data

<xsl:value-of select="LicenseExpirationMonth1"/>/<xsl:value-of select="LicenseExpirationYear1"/>

Produced (Example) this:

However...when there's no data I get the / mark...which I don;t want.

How do I wrap that to only show the / when there's data?

some notes
- normalize-space() I do that to cast the element to string and remove trailing whitespace (basically I do this to make sure that a single space would still return fale)
- why not test="not(normalize-space(LicenseExpirationMonth1) = '')"> ? Well, a string expression used as a boolean expression returns false if the string expression resolves to an empty string
- why xsl:if and not xsl:choose? You would use xsl:choose when there are multiple conditional branches or if you would have an "else" clause (which would be xsl:otherwise in the choose)
<xsl:if test="..."></xsl:if> is short for
<xsl:choose><xsl:when test="..."></xsl:when></xsl:choose>
(or xsl:if is short for an xsl:choose with only one xsl:when and no xsl:otherwise)

Ah, I did not spot the second value-of, good catch zc2
Gertone (Geert Bormans)

well, no problem,
though mine would have the desired effect (you likely don't want the '/' if the Month is not there and the year is) I consider zc2's solution more correct.
