           Summary: xmllint complains about element Model: validity error
                    : Syntax of value for attribute xmi.id of Model is not
                    valid"
    Classification: Applications
           Product: umbrello
           Version: unspecified

            Blocks: 415989
  Target Milestone: ---

When checking the validation support for xmi files requested on
https://bugs.kde.org/show_bug.cgi?id=3D415989#c2, problems occurred in conn=
ection
with xml attributes of type ID and IDREFS.

STEPS TO REPRODUCE
1. git clone umbrello sources from [email protected]:sdk/umbrello.git
2. checkout branch release/25.04
3. enter checked out directory
3. run `tools/lint-xmi-files models/diagrams/class`

OBSERVED RESULT
The tools started in 3. prints out=20

SOFTWARE/OS VERSIONS
Operating System: openSUSE Leap 15.6
KDE Plasma Version: 5.27.11
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.12

ADDITIONAL INFORMATION
According to
https://www.liquid-technologies.com/Reference/Glossary/DTD_Datatypes_ID.html
there are some limitations for valid ID and IDREFS values:=20=20

    It must conform to the EBNF for "Name". In simple terms this means a "N=
ame"
has to start with a letter or ':' or '_'. The rest of the characters must be
numbers, letters ':', '_', '-', or '.' it can not contain any spaces.

For example, since =E2=80=9CLogical View=E2=80=9D is used here as the value=
 for the 'xmi.id'
attribute, the problem is that the value contains spaces, which is not
permitted.
Other examples are:

    <UML:Model stereotype=3D=E2=80=9Cfolder=E2=80=9D ... xmi.id=3D=E2=80=9C=
Use Case View=E2=80=9D name=3D=E2=80=9CUse Case
View=E2=80=9D>
    <UML:Model stereotype=3D=E2=80=9Cfolder=E2=80=9D ... xmi.id=3D=E2=80=9C=
Component View=E2=80=9D name=3D=E2=80=9CComponent
View=E2=80=9D>
    <UML:Model stereotype=3D=E2=80=9Cfolder=E2=80=9D ... xmi.id=3D=E2=80=9C=
Deployment View=E2=80=9D
name=3D=E2=80=9CDeployment View=E2=80=9D>
    <UML:Model stereotype=3D=E2=80=9Cfolder=E2=80=9D ... xmi.id=3D=E2=80=9C=
Entity Relationship Model=E2=80=9D
name=3D=E2=80=9CEntity Relationship Model=E2=80=9D>

The problem with IDREFS occurs with references that contain spaces, which
occurs, for example, with the 'namespace' attribute as shown below:

      <UML:Package stereotype=3D"folder" namespace=3D"Logical View" ... "
xmi.id=3D"Datatypes" name=3D"Datatypes">
