Hi Wanda.

My company purchased Ken Holman's "Practical Transformation Using XSLT
and XPath Video".

I like having it around so I can just pop it in when I get stumped and
need to review specific portions.

I can understand the desire to have dita-focused training. In my
opinion, a thorough understanding of xslt and xpath principles and
functions will serve me better in the long run, especially as we move
towards an increasingly customized publishing pipeline (for
specialization, etc.).
