Extracting data from XMLType field

Question

Sorry, I don't know XMLQuery very well, this is probably a simple question.  I'm trying to extract data into a tablular form from an XMLTYPE field.  I'll use the following example to illustrate my question:
WITH a as (
select xmltype('
<bugStatus>
  <status>
    <bugCode>111</bugCode>
    <bug number="12345" description="Low severity bug"/>
  </status>
  <status>
    <bugCode>222</bugCode>
    <bug number="67890" description="High severity bug"/>
  </status>
</bugStatus>
') xmldata from dual)
SELECT x.*
FROM a, xmltable('bugStatus/status'
   passing a.xmldata columns
   status_code number path 'bugCode'
) x;
Running that code block extracts the "bugCode" fields successfully.  But I'd like to also similarly extract the "bug number" and "description" fields.  Ideally as independent columns.  But even if only as a single line showing "bug number=.... description=....." I could then still parse it with SQL.
Can someone please point me in the right direction of how I can also extract that additional data?
Thanks!

Thanks Marco, that was a great and simple solution to my original question.
However let me change the data slightly.  I've tried to do something similar with this slightly modified XML data and I think I'm close, but not quite there.  Can you assist with this new scenario?
WITH a as (
select xmltype('
<bugStatus>
   <bugCode REF_ID="XYZ">
      <status>
          <bug number="12345" description="Low severity bug"/>
          <bug number="67890" description="High severity bug"/>
      </status>
   </bugCode>
</bugStatus>
') xmldata from dual)
SELECT /*x.bugCode,*/ y.bugNumber, y.bugDescription
FROM a,
     xmltable('/bugStatus'
        PASSING a.xmldata
        COLUMNS
           bugCode char(3) path 'bugCode/@REF_ID',
           mystatus xmltype path 'bugCode/status'
     ) x,
     xmltable('/status'
        PASSING x.mystatus
        COLUMNS
           --row_number for ordinality,
           bugNumber number path 'bug/@number',
           bugDescription varchar2(80) path 'bug/@description'
     ) y;
I think I'm close on this one but still getting the error:
ORA-19279: XPTY0004 - XQuery dynamic type mismatch: expected singleton sequence - got multi-item sequence
Thank you!
