well neither Xalan nor xsltproc complains :(
Same results for both... (even with the permutation)

If you set the verbose mode to xsltproc, you have

$ xsltproc -v s05b.xsl xml05.xml
Added namespace: xsl mapped to http://www.w3.org/1999/XSL/Transform
xsltPrecomputeStylesheet: removing ignorable blank node
xsltParseStylesheetProcess : found stylesheet
xsltCompilePattern : parsing '//para'
xsltCompilePattern : parsed //para, default priority 0.000000
added pattern : '//para' priority 0.000000
xsltCompilePattern : parsing 'chapter/para'
xsltCompilePattern : parsed chapter/para, default priority 0.500000
added pattern : 'chapter/para' priority 0.500000
parsed 2 templates



added pattern : '//para' priority 0.000000
added pattern : 'chapter/para' priority 0.500000

hummm... Then this is a bug ?

cheers
