I think the logic you are trying to describe is

<xsl:attribute name="claimable"
  select="some $v in $docA/vendors/vendor satisfies starts-with($v,
@name)"/>

or if you prefer 1.0 syntax

<xsl:attribute name="claimable">
  <xsl:value-of select="boolean($docA/vendors/vendor[starts-with(.,
current()/@name)])"/>
</xsl:attribute>

That may not perform well, but get it working first and then worry about
speeding it up.
