I am fairly new to xslt 3.0 and have a problem that requires it’s use. I am very close but my output is printing the text-only copy of the data that I do not want.
I have to basically merge the T3 Block with the T4 Block only for workers that have Employee IDs and have to get the Header data also.

Desired Output: Note here that since Matt Carp doesn’t have an Employee ID, I do not want him on the Output. However my code above seems to print out all his T4 Block in one string like so: 4xyz333MATTHEWCARP

It might suffice to declare <xsl:mode name="in-memory" on-no-match="shallow-skip"/>.

This isn’t an answer to your question but a comment on your this:ApplyMap function, which appears to have a bug.
<xsl:function name="this:ApplyMap">
<xsl:param name="externalValue"/>
<xsl:param name="mapName"/>
<xsl:variable name="internalValue">
<xsl:value-of select="is:getIntegrationMapValue(string($mapName),string($externalValue))"/>
</xsl:variable>
<xsl:choose>
<xsl:when test="$internalValue">
<xsl:value-of select="$internalValue"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$externalValue"/>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
Note that the variable internalValue, because it has no select attribute, and no as attribute, acquires its value from its content (a “sequence constructor”), and because the xsl:value-of statement produces a single string you might think the variable would end up as a string value, but it doesn’t. In fact, when a variable has no declared type (as attribute) and its value is defined using a sequence constructor, the resulting sequence is wrapped in a document node. So in your case, if the is:getIntegrationMapValue() function returned a string "foo", your $internalValue variable would be a plain text document containing the text foo. If is:getIntegrationMapValue() returned a zero-length string, the $internalValue variable’s value would be an empty document node.
The reason this is important is that you then treat this variable as a boolean, and whereas the boolean value of a string is false if the string is zero-length, the boolean value of an empty document (i.e. a document node containing no text) is true (in fact the boolean value of any node is always true). Of course this means that the following xsl:choose will always select the xsl:when and never the xsl:otherwise.
One possible fix would be to add an as="xs:string" to the variable. Or you could replace the xsl:variable‘s sequence constructor with a select attribute (or you could do both):
<xsl:variable name="internalValue" select="is:getIntegrationMapValue(
string($mapName),
string($externalValue)
)"/>
Personally, I would probably drop the xsl:variable, xsl:choose, xsl:when, and replace it with a single XPath expression; something more like this:
<xsl:function name="this:ApplyMap">
<xsl:param name="externalValue"/>
<xsl:param name="mapName"/>
<xsl:value-of select="
let $internal-value:= is:getIntegrationMapValue(
string($mapName),
string($externalValue)
)[normalize-space()]
return ($internalValue, $externalValue)[1]
"/>
</xsl:function>
… but that’s because I have a general policy of using XPath expressions with variables, loops, etc, in place of xsl:* elements, for brevity and clarity. Not everyone feels the same way.
