the new functionality for processing simple text using regular expressions
is very useful. However, I wonder why it is restricted to one expression
per instruction.

A more powerful instruction could allow multiple regular expressions that
will be processed in lex-like manner [1]. That means the regex attribute
would be a property of xsl:matching-substring and not of xsl:analyze-string.
Replacing multiple substrings with proper markup then would require less
nested XSLT elements. Having only one xsl:matching-substring in this new 
semantics would behave exactly like the current version. 

Moreover, I believe this model reflects the template model of XSLT for
text processing: xsl:analyze-string is a container like xsl:stylesheet,
xsl:matching-substring is the counterpart for xsl:template.

I would be great if this enhancement of xsl:analyze-string could be
considered for the final XSLT specification.

Best regards,
Oliver Becker
