I'm querying XMLTV data. It looks like it is currently impossible to select a path named "desc".

How can I escape 'desc' as it seems that it is a reserved word whatever the context where it is used? I tried double quotes (like in SQL) without success.

Here is a working YQL query:
select channel,title,start from xml where url='http://xmltv-fr.appspot.com/telerama.xmltv' and itemPath='/tv/programme'

Here is one that is not working:
select channel,title,start,desc from xml where url='http://xmltv-fr.appspot.com/telerama.xmltv' and itemPath='/tv/programme'

Here is the original content :
select * from xml where url='http://xmltv-fr.appspot.com/telerama.xmltv' and itemPath='/tv/programme'
