Re: For-each and keys()

key() returns all the nodes that match the key _in the current document_
so if you want to look up keys in a different document then (in xslt1)
you need touse  xsl:for-each  to make that document current.
In XSLT2 you could equivalently go
<xsl:value-of select="$Definitions/count(key('oldID',$current))
or
<xsl:value-of select="count(key('oldID',$current,$Definitions))

Ahh, if only. The for-each you mention is what I am attempting,
however, I've gotten no better idea than that (The How gets me, not
the What).

If $Definitions is defined using document() then it will represent a
well formed document so there can be at most one top level element
(presumably <disabilities>) so I do not see what you can mean by "other
branches"

You seem to know, given the way you mention for-each. Perhaps then you
can tell me where the code I have errs.

<xsl:key name="options" match="option" use="@type" />
<xsl:key name="oldID" match="option" use="@oldID" />
<xsl:template match="Record" mode="x">
	<xsl:param name="type" />
	<tr>
		<td>
			<xsl:value-of select="$type" />
		</td>
		<td>
			<xsl:variable name="current" select="disabPrimary" />
			<xsl:for-each select="$cilDefinitions">
				<xsl:value-of select="count(key('oldID',$current))" />
			</xsl:for-each>
		</td>
	</tr>
</xsl:template>
<xsl:template match="/" >
			<table>
				<xsl:for-each
select="$Definitions/disabilities/option[generate-id(.)=generate-id(key('options',@type)[1])]">
					<xsl:sort select="@type"/>
					<xsl:apply-templates mode="x" select="$vP2/Records/Record">
						<xsl:with-param name="type" select="@type" />
					</xsl:apply-templates>
				</xsl:for-each>
			</table>
</xsl:template>
