Summary: xml schema for description is invalid

Initial Comment:
example for a build file:
  <project xmlns="http://nant.sf.net/release/0.91-alpha2/nant.xsd" name="a">
    <description>my description</description>
  </project>
This will note the text between the description tags as invalid. 

I suggest to fix the content of nant.xsd file by one of the followings:

Replace: <xs:complexType name="NAnt.Core.Tasks.DescriptionTask">
by  <xs:complexType name="NAnt.Core.Tasks.DescriptionTask" mixed="true">

or

replace the occurrences of <xs:element name="description" type="nant:NAnt.Core.Tasks.DescriptionTask" />
by  <xs:element name="description" type="xs:string" />

It's been awhile...

I took a look in the source and I think I got it.  It looks like an easy
fix.  One question, is there any other complex types that need this
modification?

That would indeed shut it up - mixed=true is what you want to get a
complextype to accept text content. However as pointed out by dogu, the
schema is autogenerated. What is really needed is a change to the schema
task to get it to apply a mixed content model when it generates xsd types
for tasks, based on some criterion. Having only just viewed Nant source for
the first time today, I don't have a clear idea how that might be
accomplished.

The Description task doesn't appear to do anything; maybe it would be as
simple as adding a 'text' property to the description task, which should
appear as a 'text' attribute in the build file? NAnt by convention seems
not to use element content to express very much at all.

I'm trying to get familiar with xsd in general.  From what I can see, the
closest I can get to the mixed is with this:

  <xs:complexType name="Target" mixed="true">
    <xs:choice minOccurs="0" maxOccurs="unbounded">
      <xs:complexType name="NAnt.Core.Tasks.DescriptionTask">

however, I don't know if that will resolve this issue.

Thanks,
Ryan

Hi, 

I stubled about this long time ago. There are some more tasks like the
echo task if I remember correctly. 
Changing this in xsd file itself would be easy. But this xsd file is
created automatically by nantschema task. So we need to find a way to
resolve this there. But this was to much effort for me and I stopped in
validating my build files with other tools than nant itself.
