XSD Enumeration used in a XSLT File

I have this XSD Enumeration :

<xs:element name="NeedEnum" type="my:Enum" />

<xs:simpleType name="Enum">
  <xs:restriction base="xs:string">
    <xs:enumeration value="Enumeration 1" id="E_1" />
    <xs:enumeration value="Enumeration 2" id="E_2" />
    <xs:enumeration value="Enumeration 3" id="E_3" />
    <xs:enumeration value="Enumeration 4" id="E_4" />
  </xs:restriction>
</xs:simpleType>

I want to be able to use this simple type/enumeration into a XSLT File to be able to have an HTML select populated with those values.

This is my XSLT File so far (just the table part, not all the namespaces) :

    <div>
     <select title="Enum" class="">
      <xsl:for-each select="Enum">
       <option>
        <xsl:value-of select="./@value"/>
       </option>
      </xsl:for-each>
      <option>
       <xsl:value-of select="NeedEnum"/>
      </option>
     </select>
    </div>

I know that my XSLT file is way off, but I would like to have a select with the value of the options being the enumeration id and the "caption" being the value of the enumeration. I mean I've been reading for a couple of hours and I didn't find anything that could've helped me.

I want to have something like this linked to my NeedEnum : 

<select title="Enum" >
 <option value="E_1" >Enumeration 1</option>
 <option value="E_2" >Enumeration 2</option>
 <option value="E_3" >Enumeration 3</option>
 <option value="E_4" >Enumeration 4</option>
</select>

Can you help me?

You haven't said anything about your processing environment, but if this is a schema-aware transformation using Saxon-EE, then when $e is bound to the (schema-validated) NeedEnum element:

let $t := saxon:type($e)

returns (a representation of) the simple type Enum

let $f := $t('facets')[.('class')='enumeration']

returns its enumeration facet

let $v := $f('values')

returns the enumeration values as a sequence of strings.

So you can write:

<xsl:for-each select="saxon:type($e)('facets')[.('class')='enumeration']('values')">
   <option value="E_{position()}"><xsl:value-of select="."/></option>
</xsl:for-each>

The id attributes in the schema, unfortunately, are not available.

(Not tested.)
