ALIAS set to  "test{1}=@xrefitem test\1 \"Test notes \1\"  \"Test notes \1\" \n" 

Have a page block containing two tests

/**
@page changelog_sb Change Log SJB.

@test{SBUR-87YKDP}
- stuff here
- more stuff

@test{SBUR-883CV7}
- and the next test
- and more

@note
- comments.
*/

If the first argument to the @test has the hyphen in the text the keys for both tests get treated the same, so although the alias should make the xrefitem keys, testSBUR-87YKDP and testSBUR-883CV7 only one entry gets made; the first one.  If the source is changed to  @test{SBUR87YKDP} and @test{SBUR883CV7} the documentation works correctly.  

I assume that the - in the key is causing SBUR-87YKDP and SBUR-883CV7 to be treated the same.
