This won't do the right thing if unittitle can end with '?', '!', or any
other punctuation character.

If unittitle can contain elements as well as text (i.e., contain mixed
content) then 'substring()' will blow up when you select multiple text
nodes.

And you'll lose the child elements, if any exist, when you do the
'normalize-space()'.

As Liam said, it's redundant to repeat the '<xsl:text>&#160;</xsl:text>'.

Assuming there are no child elements but the title can end with other
punctuation characters:

<xsl:value-of select="normalize-space(archdesc/did/unittitle)"/>
<xsl:if test="not(matches(normalize-space(archdesc/did/unittitle),
'[.?!]$'))">
  <xsl:text>.</xsl:text>
</xsl:if>
<xsl:text>&#160;</xsl:text>
