Need to override previously copied attributes etc.

I have a stylesheet which basically should do the following:
- Copy the whole XML file passed to it
- Apply a template if the element is "field"
        - Copy everything over from the XML file passed
        - Then start copying everything from the XML in a variable
($fieldCollection) where the attribute "identity" matches
                - However if the element from $fieldCollection contains
an attribute called "reference" is present it needs to copy everything
from the element in $fieldCollection that matches that "identity"
                - Then it just needs to copy over that element from
$fieldCollection and overwrite any attributes previously copied
                - And finally it needs to copy over the element from the
XML passed in and overwrite anything previously there

The file for $fieldCollection

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- Author: Taco Fleur (tacofleur(_at_)gmail(_dot_)com) -->
<root>
        <field 
                name="bit" 
                identity="5AB56CAB-D9DD-713A-D3EE45FAABF02F95" 
                valid="01"
                type="boolean">
                <option value="0" />
                <option value="1" />
        </field>
        <field 
                name="principalPlace" 
                identity="5AB5F3AD-D9DD-713A-D582F669F41CFAA8"
                reference="5AB56CAB-D9DD-713A-D3EE45FAABF02F95" />
</root>

The XML file passed in

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- Author: Taco Fleur (tacofleur(_at_)gmail(_dot_)com) -->
<root>
        <form name="address">
                <segment value="01">
                        <step value="a">
                                <field 
        
identity="5AB5F3AD-D9DD-713A-D582F669F41CFAA8" 
                                        required="true" 
                                        display="Is Principal Place of
Business" />
                        </step>
                </segment>
        </form>
</root>

What I would like to end up with is


<root>
        <form name="address">
                <segment value="01">
                        <step value="a">
                                <field 
                                        name="principalPlace"
<- Copied from variable
        
identity="5AB5F3AD-D9DD-713A-D582F669F41CFAA8"  <- Copied from variable
                                        required="true"
<- Copied from file passed in
                                        display="Is Principal Place of
Business"               <- Copied from file passed in
                                        valid="01"
<- Copied from reference element in variable
                                        type="boolean">
<- Copied from reference element in variable
                                        <option value="0" />
<- Copied from reference element in variable
                                        <option value="1" />
<- Copied from reference element in variable
                                </field>
                        </step>
                </segment>
        </form>
</root>

Hope that makes sense and someone can help?

Thanks
