patent references in EMBL

We have been adding sequences from patents to EMBL over the last year.
These have a reference of the form:
RN   [1]
RP   1-51
RA   ;
RT   "DNA EXPRESSION SYSTEMS BASED ON ALPHAVIRUSES";
RL   Patent number WO9210578-A/26, 25-JUN-1992.
XX
...
Which was not parsed  and terefor not searchable.
I corrected the parser in embl.sdl 
old:
----
 reference  = ? ref | {~ ~ <not>};
 ref        = ~A-Za-z .\-_~ <wrt c=@JNL> ~0-9~ <wrt c=@VOL> ':'
               ~0-9~ <wrt c=@PP> '-' <app c=@PP> ~0-9~
               '(' ~0-9~ <wrt c=@YEAR> ')';
-----
new:
-----
 reference  = ? patent | ref | {~ ~ <not>};
 ref        = ~A-Za-z .\-_~ <wrt c=@JNL> ~0-9~ <wrt c=@VOL> ':'
               ~0-9~ <wrt c=@PP> '-' <app c=@PP> ~0-9~
               '(' ~0-9~ <wrt c=@YEAR> ')';
 patent     = 'PATENT NUMBER' <wrt> ~A-Z0-9\-/~ <wrt> ',' ~0-9A-Z\-~ '.';
-----
This now allows queries like 
getz  '[embl-ref: patent*]'
getz '[embl-ref: patent*] and [embl-ref: wo921*]'

Similar queries can be performed in our WWW and SRS-FTP interfaces
