           </dmTitle>
        </dmRefAddressItems>
     </dmRef>
  </pmEntry>
    </content>
    </pm>

And these two variables:

<xsl:variable name="all-DMs" as="item()*" select="descendant::content/pmEntry//dmRef/dmRefIdent/dmCode"/>

<xsl:variable name="flight-DMs" as="item()*" select="descendant::content/pmEntry//dmRef/dmRefIdent/dmCode[@infoCode=('130','131')]"/>

$flight-DMs looks like this, $all-DMs contains all the dmCodes:

<dmCode assyCode="00" disassyCode="00" disassyCodeVariant="E01" infoCode="130"
                  infoCodeVariant="D" itemLocationCode="A" modelIdentCode="555"
                  subSubSystemCode="0" subSystemCode="3" systemCode="15" systemDiffCode="A"/>
 <dmCode assyCode="00" disassyCode="00" disassyCodeVariant="E02" infoCode="130"
                  infoCodeVariant="D" itemLocationCode="A" modelIdentCode="525"
                  subSubSystemCode="0" subSystemCode="3" systemCode="15" systemDiffCode="A"/>
 <dmCode modelIdentCode="FLRA" systemDiffCode="A" systemCode="00" subSystemCode="0" subSubSystemCode="0" assyCode="00" disassyCode="00" disassyCodeVariant="E01" infoCode="131" infoCodeVariant="T" itemLocationCode="A"/>

I would like to process $flight-DMs first and then the rest of the DMs with $all-DMs but excluding any dmCode that was already processed in $flight-DMs. I thought the best way was to create a third variable, $filtered-DMs that contained $allDMs - $flight-DMs, (actually I would prefer one variable that contained $flight-DMS and $filtered-DMs so I only have to loop once) but my attempts have failed:

    <xsl:variable name="filtered-DMs" as="item()*" select="$all-DMs[not(.=$flight-DMs)]"/>
<xsl:variable name="filtered-DMs" select="every $x in $all-DMs satisfies not($x=$flight-DMs)"/>

If I try to use contains() or matches() I get an error that the second parameter can't contain more than one sequence:

<xsl:for-each select="every $x in $all-DMs satisfies not(contains($flight-DMs,$x))">

EDIT: I think what I want is:

<xsl:variable name="filtered-DMs" as="item()*" select="$flight-DMs union $all-DMs"/>

I think you want e.g. every $item1 in $sequence1 satisfies not(some $item2 in $sequence2 satisfies contains($item1, $item2))

Given these variables

<xsl:variable name="flightCodes" as="xs:string*" select="('130','131')"/>
<xsl:variable name="all-DMs"     as="element()*" select="descendant::content/pmEntry//dmRef/dmRefIdent/dmCode"/>
<xsl:variable name="flight-DMs"  as="element()*" select="$all-DMs[@infoCode=$flightCodes]"/>

you have 2 options for flight-DMs

<xsl:variable name="non-flight-DMs" as="element()*"    select="$all-DMs[not(@infoCode=$flightCodes)]"/>

<xsl:variable name="non-flight-DMs" as="element()*"    select="$all-DMs except $flight-DMs"/>
