I think it very appropriate.

A few have been posted. The "XSLT two to three" course i've run in
person assumes basic XSLT, but i don't yet have that online. When i do,
probably next month, i plan to add some help for XSLT 1 users, since
people can't stop and ask questionsB9.

Probably the biggest differences to learn in the move from XSLT 1 to
either 2 or 3 are...
* value-of should have been <xsl:text select=..../> really
* sequences and types
* XSLT functions
* massively bigger function library
* a few idioms, such as (e1, e2)[1] and if..then...else in XPath
* a few differences, such as string(seq) no longer using only the first
item in the sequence

Although i don't think it necessary to become proficient in XSLT 2
before learning XSLT 3, a course focusing on what's new in 3 won't talk
about grouping, tunnel parameters, the uses of types for variables, and
so on. But the more of that the teacher adds, the longer the course.

B9 Note: ibm finding it harder than i expected to move from custom
courses or courses very tailored to the attendees, to television mode.
People expect to pay much less for prerecorded courses, quite
reasonably, but i think attendees get less out of them. A chemistry
teacher i had used to say, bTo read is to forget; to see is to
remember; to do is to learnb which is why we do experiments. Seeing a
room of people run 9,000+ transformations in a few seconds using
fn:transform(). or understanding accumulators, reminded me of this.

A mixture of pre-recorded sessions and QA sessions might be a
compromise, or possibly hiring someone to do a one-day custom
interactive session after people have done a course. What do you think?
Or are my concerns without merit and TV-style is fine?
