Describe the bug
I encountered XMLSyntaxError when trying to reproduce the text summarization example.
To Reproduce
Steps to reproduce the behavior:
Rail spec:
<rail version="0.1">
<script language='python'>
document = open("search.txt", "r").read()
</script>
<output>
<string
name="summary"
description="Summarize the given document faithfully."
format="similar-to-document: {document}, 0.60"
on-fail-similar-to-document="filter"
/>
</output>
<prompt>
Summarize the following document:
{{document}}
@complete_json_suffix
</prompt>
</rail>(I only changed the document path, which is a valid path for me.)
Running the command
guard = gd.Guard.from_rail_string(rail_str)
gives the following error:

Expected behavior
The Guard should be created with no errors.
Library version:
Installed directly from GitHub, main branch.
Additional context
Removing the
format="similar-to-document: {document}, 0.60"
on-fail-similar-to-document="filter"
doesn't throw an error, but that would defeat its intended purpose.
FWIW, switching to the saliency-check validator throws the same error.
