Find distinct values across each node in xslt1.0 - xslt-1.0

Question

I want to find distinct values across each node. but when i use muenchian method it will select distinct values only at top level.
Currently i am getting output as:
Bag 20
Tray 30
But i want to group type and quantity for each item
<!--for 1st item-->
Bag 20
Tray 30
<!--for 2nd item-->
Bag 20
Box 20
Tray 30
I am doing some research to make it work but did not succeed.
XML:
<?xml version="1.0" encoding="UTF-8"?>
<Test>
<Items>
<Item>
<name>A</name>
<type>Bag</type>
<input quantity="20"/>
</Item>
<Item>
<name>A</name>
<type>Bag</type>
<input quantity="20"/>
</Item>
<Item>
<name>B</name>
<type>Metal</type>
<input quantity="20"/>
</Item>
<Item>
<name>A</name>
<type>Tray</type>
<input quantity="30"/>
</Item>
</Items>
<Items>
<Item>
<name>A</name>
<type>Bag</type>
<input quantity="20"/>
</Item>
<Item>
<name>A</name>

Appreciate your help!

If - as it seems - you want to find distinct Items whose name is A by their type separately for each Items, then you need to include the parent Items' id in the key. Here's a simplified example:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="k" match="Item[name='A']" use="concat(type, '|', generate-id(..))"/>
<xsl:template match="/Test">
<root>
<xsl:for-each select="Items">
<xsl:comment>
<xsl:value-of select="position()" />
</xsl:comment>
<xsl:for-each select="Item[name='A'][count(. | key('k', concat(type, '|', generate-id(..)))[1]) = 1]">
<item>
<type>
<xsl:value-of select="type"/>
</type>
<quantity>
<xsl:value-of select="input/#quantity"/>
</quantity>
</item>
</xsl:for-each>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
Applied to your input example, the result will be:
Result
<?xml version="1.0" encoding="UTF-8"?>
<root>
<!--1-->
<item>
<type>Bag</type>
<quantity>20</quantity>
</item>
<item>
<type>Tray</type>
<quantity>30</quantity>
</item>
<!--2-->
<item>
<type>Bag</type>
<quantity>20</quantity>
</item>
<item>
<type>Box</type>
<quantity>20</quantity>
</item>
<item>
<type>Tray</type>
<quantity>30</quantity>
</item>
</root>
