Section 43.4 stringparams
To pass stringparams to xsltproc, use a command like the following (possibly with
xsltproc -o animals.tex --stringparam latex.font.size "20pt" /path/to/xsl/pretext-latex.xsl ~/books/aota/animals.xml
You can use as many stringparam as you like on the command-line (or in your scripts). The quotation marks are not strictly needed in this example, but if the value of the parameter has spaces, slashes, etc. , then you need to quote-protect the string from the command-line processor, and either single or double quotes will work (and protect the other kind).
