In order for clinical guidelines to be verified, they must first be acquired
or at least translated into a format that can be treated formally. Most
guidelines today either exist as plain text, tables, or flow-charts.

We present two tools that support this translation: The Guideline Markup
Tool (GMT) and the Pontifex Intelligent XML Editor Extension (PIXEE).
The GMT provides a relatively easy way to translate
free text into Asbru. It does this by displaying both the original
text and the translation, and showing the user which parts of the Asbru
code correspond to which elements of the original text. This not only
makes it easier to author plans, but also to understand the resulting Asbru
constructs in terms of the original guideline.

PIXEE is a more general XML editor that has some special features due to
a richer representation of the language than pure XML. It provides means to
aggregate information dynamically and also to more effectively work with
language constructs.

Both these tools make the translation into a formal language easier and
therefore enable us to formally verify guidelines, thus reducing errors
and ambiguities in them.
