Sorry : )
Structure is:
<in_proc>
<row />
<row />
...
</in_proc>
In that case, this:
<xsl:template match="/">
<in_proc>
<xsl:apply-templates select="row"/>
is clearly wrong, because the document node does not have a child called
"row".

That tells me absolutely nothing about the structure of either.
Let's be concrete. Is the outermost element of your source
XML caled <row>
or is it called <in_proc>? If it's called <row> then I can
point to one set
of errors in your stylesheet, if it's called <in_proc> then
I can point to a
different set. It's possible that your stylesheet is
written to allow it to
be either, but that seems unlikely.

xm data param may or may not contain new
data. This data is appended to the xml source when it is
new. There
is an id column named "activityid" which allows me a guarantee of
unique matches.

This seems unlikely.
I'm still a little confused on the parm(s) but no worries!

<xsl:template match="row">
<xsl:copy-of select="."/>
</xsl:template>
is equivalent (but slower, probably) to
<xsl:copy-of select="row"/>
it just copies all the row elements. In this case
however it prduces
nothing as there are no row element children of the current
node (the
only child of / is a in_proc element (I guess, you have not
shown your
input format)
<xsl:if test="$current_id = $activity_id">
this test is always true (given the default value of $xm)
as $current_id
is an attribute node from the set $activity_id
Even if you supply an xm parameter so that the tests
may be false,
<xsl:apply-templates select="$xm/row" mode="append"/>
<xsl:template match="row" mode="append">
<xsl:variable name="current_id" select="@id"/>
<xsl:if test="$current_id = $activity_id">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:template>
is equivalent to
<xsl:copy-of select="$xm/row[(_at_)id = $activity_id]"/>
