Two ways come into mind:

1. Have the following in your code globally defined:

<someprefix:Values>
  <Value>bob<Value>
  <Value>joe<Value>
  <Value>ben<Value>
</someprefix:Values>
  
Assign this to an xsl:variable like this:

<xsl:variable name="vValues" select="document('')/*/someprefix:Values"/>

Then your test will be:

@name = $vValues/Value

When a string is compared to a node-set, the comparison is true if a node (from the
node-set) exists for which the comparison is true.

2. You can use the id() function -- look at:
