Could someone else inspect?

Half of the solutions I've received used two (one nested) key
functions, and half didn't.

Here is the current progress:

Hey group,

Trying to come up with key declarations for the below XML trees (which
are both contained within $variables

At the end of the day, I need output that resembles

        <output type="Cognitive"  count="50" />
        <output type="Physical"  count="26" />
        <output type="Visual"  count="34" />
        <output type="Hearing"  count="90" />
        <output type="Mental"  count="11" />
        <output type="None"  count="1" />

The count, in this case, is the amount of times a Record/disabPrimary
corresponds to any disabilities/option/@oldID.  These must then be
grouped by their @type and appear only once in the table.

Sorry to post so much but in trying to score for brevity I have
obviously overcorrected and gone straight to muddled ambiguity in
previous posts. Please let me know if there is anything too vague that
I may elaborate upon.

My current XSL has the problem of not using key in a meaningful way
(always returns 0) and also produces a row for each Record, although
it does order them by type.

XSL goes something like:

<xsl:key name="options" match="option" use="@type" />
<xsl:key name="oldID" match="Record" use="disabPrimary" />
<xsl:variable name="$Definitions" select="Document(Disabilities.xml)" />
<xsl:variable name="$Var" select="Document(Records.xml)" />
<xsl:template match="Record" mode="x">
        <xsl:param name="type" />
        <tr>
                <td>
                        <xsl:value-of select="$type" />
                </td>
                <td>
                        <xsl:variable name="current" select="disabPrimary" />
                        <xsl:for-each select="$Definitions/disabilities">
                                <xsl:value-of select="count(key('oldID',$current))" />
                        </xsl:for-each>
                </td>
        </tr>
</xsl:template>
<xsl:template match="/" >
        <html>
                <head>
                        <link rel="stylesheet" href="performance.css" />
                </head>
                <body>
                        <table>
                                <xsl:for-each
select="$Definitions/disabilities/option[generate-id(.)=generate-id(key('options',@type)[1])]">
                                        <xsl:sort select="@type"/>
                                        <xsl:apply-templates mode="x" elect="$Var/Records/Record">

                                        </xsl:apply-templates>
                                </xsl:for-each>
                        </table>
