[BioC] problem with xps and annotation file from affymetrix mirna array

Dear Giacomo,

Steve Shen was so kind to set up centralized scheme file repository at:
http://microarray.bu.edu/~sshen/xps/
so you can download now the scheme "mirna10.root" from this repository.
An official announcement of the availability will follow once the scheme 
list is complete.

Best regards
Christian
