How to limit attribute's (string) length?

[god_prophet]

According to documentation, performance wise, it is better to limit/indicate the length of the fields/attributes. 

How to do so?

Currently I have this in the XML definition: 

<attribute label="Código Interno Computacional" name="CODINTERNOCOMPUTACIONAL"
type="string"/>

Adding: value="50" results in error.

Also, inspecting xtk:srcSchema, I see the attributes don't have a length value:

<!-- should be a template "xtk:common:name" -->
<attribute default="NewName()" edit="NamePkEdit" label="Name" name="name" required="true"
type="string"/>


My Schema structure:

<srcSchema _cs="DTI_XXX (abc)" created="2024-08-26 19:36:36.581Z" createdBy-id="0"
entitySchema="xtk:srcSchema" img="xtk:schema.png" label="DTI_XXX"

lastModified="2024-09-06 03:50:16.385Z" mappingType="sql" md5="AF12309BC7EC4DD0D7B62A928E490687"
modifiedBy-id="0" name="DTI_XXX" namespace="abc" xtkschema="xtk:srcSchema">
<createdBy _cs="c (cccc)"/>
<modifiedBy _cs="c (cccc)"/>

<element autopk="true" label="DTI_XXX" name="DTI_XXX">

<attribute label="aaa" name="aaa" type="string"/>
</element>
</srcSchema>

Hi @god_prophet ,

To define length of a striing, use length=""

Example,

<attribute label="aaa" name="aaa" length="50" type="string"/>
